TPLP2985-33DBVR

TECH PUBLIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPLP2985-33DBVR from TECH PUBLIC, in a SOT-23-5. 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 VIN power_in Input supply voltage pin. Operating range 2.0V to 20V (absolute max 24V to GND). Bypass with a 1µF ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference. Typical quiescent (ground) current is 2µA at no load.
3 EN input Enable control input. Drive above V_IH (min 1.1V) to enable the regulator; drive below V_IL (max 0.4V) to shut it down. EN input current ~10nA typ (V_EN=27V). Do not float.
4 NC unconnected No internal connection. May be left floating or tied to GND for mechanical stability.
5 VOUT power_out Regulated output of the LDO. Fixed 3.3V (±2%) at up to 150mA. Requires a 1µF ceramic output capacitor to GND for stability. Dropout ~0.2V at 50mA (V_OUT=3.3V).
