TPRT9161-50GV

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

TPRT9161-50GV from TECH PUBLIC, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground / common return (接地端) for the regulator. Tie directly to the system ground plane; carries the small quiescent current plus any load current that returns via GND.
2 VOUT power_out Regulated 5.0 V output (输出端). Sources up to 300 mA with typical 160 mV dropout at 100 mA. Requires a ceramic output capacitor (1 µF typical, per the typical-application circuit) for stability and transient response; internal auto-discharge is enabled through the control block.
3 VIN power_in Unregulated supply input (电源端). Operates up to 18 V absolute maximum. Bypass to GND with a 1 µF ceramic capacitor placed close to the pin (per the typical-application circuit).
