PJ9350L28DE

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · DFN-4L(1x1)

PJ9350L28DE from PJSEMI, in a DFN-4L(1x1). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output of the fixed 2.8 V variant (PJ9350L28DE); a minimum 1uF output capacitor is required for stability and the maximum output current is 300mA.
2 GND power_in Ground reference pin; input and output capacitors must return to a clean analog ground.
3 EN input Active-high chip enable with VENH minimum 1.2V, VENL maximum 0.4V, input current maximum 1.0uA, and the datasheet notes this pin is high impedance.
4 VIN power_in Power input with a supply range of 2.5V to 6.5V (absolute maximum -0.3V to 8V), which must stay above VOUT for the device to regulate.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
