SSP7615-33M5R

Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

SSP7615-33M5R from Shanghai Siproin Microelectronics, 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. Accepts 1.5V to 8V (absolute max -0.3 to 8V). Bypass to GND with a 1uF ceramic capacitor close to the pin.
2 GND power_in Ground reference for the regulator. Connect directly to the system ground plane.
3 EN input Active-high enable input. VENH >= 1.2V enables the regulator; VENL <= 0.4V shuts it down (<1uA shutdown current). Must not be left floating. IEN <= 1uA over 0-5.5V.
4 NC unconnected No internal connection. May be left floating or tied to ground.
5 VOUT power_out Regulated output voltage pin. For the -33M5R variant this is a fixed 3.3V output capable of 400mA (450mA absolute max) with 200mV dropout at 100mA. Requires a 1uF output capacitor (tantalum or ceramic) to GND close to the pin for loop stability.
