PJ9193M25SE

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

PJ9193M25SE from PJSEMI, 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 Power input voltage. Operating range 2V to 6.5V (absolute max -0.3V to +7V). Bypass to GND with a 1µF ceramic capacitor placed as close as possible to the pin for stability and noise decoupling.
2 GND power_in Ground reference for the regulator. Return path for input and output capacitors; route with a wide, short copper trace back to this pin to minimize parasitic inductance/resistance.
3 EN input Chip Enable, active high. CMOS logic input: VIH ≥ 1.2V starts up the regulator, VIL ≤ 0.4V shuts it down. Leakage typ. 1µA. High impedance pin - cannot be left floating; may be tied to VIN to keep the part always on.
4 NC unconnected No internal connection. Leave floating or tie to GND/VIN as convenient for layout; not electrically bonded to the die.
5 VOUT power_out Regulated output voltage. Fixed 2.5V for the -25 option, up to 300mA (M current tap). Requires a minimum 1µF ceramic output capacitor (X5R/X7R) placed close to VOUT and GND for stability. Current limit typ. 450mA; short-circuit current typ. 50mA.
