TPS7A0528PDBZR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

TPS7A0528PDBZR from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground pin. This pin must be connected to ground on the board.
2 OUT power_out Regulated output pin. A capacitor from OUT to ground is required for stability, with COUT of 0.47 µF minimum to 22 µF maximum per the Recommended Operating Conditions.
3 IN power_in Input supply pin, rated 1.4 V to 5.5 V per the Recommended Operating Conditions, with an input capacitor placed as close to the device as possible.
