TPRT9078-18GJ5

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

TPRT9078-18GJ5 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. Operates over 1.2V to 5.5V (absolute max -0.3V to 6.5V). Bypass with a 1µF ceramic capacitor to GND close to the pin.
2 GND power_in Device ground reference. Ground current is typically 2µA at no load; shutdown ground current is typically 0.1µA (max 0.5µA).
3 EN input Enable control input. VIH ≥ 1.0V enables the regulator; VIL ≤ 0.4V places the device in shutdown. Input current is typically 10nA at VEN=5V (max 100nA). Absolute max -0.3V to 6V referenced to GND.
4 NC unconnected No internal connection. Leave floating or tie to GND at the board level; not bonded inside the package.
5 VOUT power_out Regulated output pin. Fixed 1.8V (±2%) for the -18 option, up to 450mA output current with dropout of ~0.28V at 300mA. Stable with a 1µF ceramic or tantalum output capacitor; internal discharge resistance of ~100Ω pulls VOUT low when disabled.
