TPAP2112K-1.8TRG1

TECH PUBLIC TPAP2112K 1 8TRG1 · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPAP2112K-1.8TRG1 from TECH PUBLIC TPAP2112K 1 8TRG1, 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. Operating range 1.2V to 5.5V (absolute max -0.3V to 6.5V). Bypass with a 1µF-10µF ceramic or tantalum capacitor to GND.
2 GND power_in Ground reference for the LDO. Quiescent ground current is 10µA typ. (shutdown ground current 0.01µA typ.).
3 EN input Enable input. VIH ≥ 2V turns the regulator on; VIL ≤ 0.6V places the device in shutdown (ISD ≈ 0.01µA typ.). EN input current 10nA typ. Absolute max -0.3V to 6V. Do not leave floating.
4 NC unconnected No connect. Leave floating or tie to GND; not internally bonded to any circuit.
5 VOUT power_out Regulated 1.8V fixed output (±2% accuracy). Delivers up to 600mA with 0.57V dropout at 600mA (VOUT=1.8V). Current-limit 1100mA typ. Requires a 1µF-10µF ceramic or tantalum output capacitor to GND for stability. 100Ω active-discharge to GND when EN=0.
