Always-on systems must have ultralow I<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">Q</span> over an extended temperature range to enable sustained operation when the vehicle ignition is off.</p><p style="box-sizing: inherit; margin-top: 0px; margin-bottom: 24px; padding: 0px; line-height: 20px;">The TPS7B81-Q1 is a low-dropout (LDO) linear regulator designed for up to 40-V V<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">IN</span> applications. With only a 2.7-µA typical quiescent current at light load, the device is an optimal solution for powering microcontrollers and controller area network and local interconnect network (CAN/LIN) transceivers in standby systems.</p><p style="box-sizing: inherit; margin-top: 0px; margin-bottom: 24px; padding: 0px; line-height: 20px;">The device features integrated short-circuit and overcurrent protection. This device operates in ambient temperatures from –40°C to +125°C and with junction temperatures from –40°C to +150°C. Additionally, this device is available in several packages of varying size and thermal conductivity. The small WSON package facilitates the most compact PCB design and the TO-252 package enables sustained operation despite significant dissipation across the device. These features make the device well suited as a power supply for various battery-connected automotive applications.</p></div><h2 class="u-header-4" style="box-sizing: inherit; margin: 0px 0px 12px; padding: 0px; font-size: 20px; line-height: 28px; font-weight: 300; color: rgb(51, 51, 51); font-family: Roboto, "Franklin Gothic Medium", Tahoma, sans-serif; font-variant-ligatures: no-common-ligatures; white-space: normal;">Features for the TPS7B81-Q1</h2><div style="box-sizing: inherit; color: rgb(85, 85, 85); font-family: Roboto, "Franklin Gothic Medium", Tahoma, sans-serif; font-size: 14px; font-variant-ligatures: no-common-ligatures; white-space: normal;"><ul style="box-sizing: inherit; margin: 0px 0px 24px 1.25rem; padding: 0px; line-height: 20px;"><li>AEC-Q100 qualified for automotive applications:</li><ul style="box-sizing: inherit; margin: 12px 0px 16px 1.25rem; padding: 0px; line-height: 20px;"><li>Temperature grade 1: –40°C to 125°C, T<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">A</span></li></ul><li>Device junction temperature range: –40°C to 150°C</li><li>3-V to 40-V wide V<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">IN</span> input voltage range with up to 45-V transient</li><li>Maximum output current: 150 mA</li><li>Low quiescent current I<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">Q</span>:</li><ul style="box-sizing: inherit; margin: 12px 0px 16px 1.25rem; padding: 0px; line-height: 20px;"><li>300 nA typical when EN = low (shutdown mode)</li><li>2.7 µA typical at light loads</li><li>4.5 µA maximum at light loads</li></ul><li>1.5% output-voltage accuracy over line, load and temperature</li><li>Maximum dropout voltage: 540 mV at 150-mA load current for fixed 5-V output version</li><li>Stable with low-ESR (0.001-Ω to 5-Ω) ceramic output-stability capacitor (1 µF to 200 µF)</li><li>Fixed 5-V, 3.3-V and 2.5-V output voltage</li><li>Integrated fault protection:</li><ul style="box-sizing: inherit; margin: 12px 0px 16px 1.25rem; padding: 0px; line-height: 20px;"><li>Thermal shutdown</li><li>Short-circuit and overcurrent protection</li></ul><li>Packages:</li><ul style="box-sizing: inherit; margin: 12px 0px 16px 1.25rem; padding: 0px; line-height: 20px;"><li>DGN (8-pin HVSSOP), R<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">θJA</span> = 63.9°C/W</li><li>DRV (6-pin WSON), R<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">θJA</span> = 72.8°C/W</li><li>KVU (5-pin TO-252), R<span style="box-sizing: inherit; font-size: 12px; line-height: 0; position: relative; vertical-align: baseline; bottom: -0.25em;">θJA</span> = 38.8°C/W</li></ul></ul></div>
