MCP1802T-3302I

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

MCP1802T-3302I 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 Unregulated supply input. Operating input voltage range 2.0 V to 10.0 V (absolute max 12 V). Requires ~1 µF ceramic bypass capacitor to GND close to the pin.
2 VSS power_in Ground / GND terminal. Common return for input, output, and SHDN reference.
3 SHDN input Active-low shutdown input (SHDN). Drive high (>=1.6 V) to enable regulator; drive low (<=0.25 V) to disable output (quiescent current drops to ~0.01 µA typ). Do not leave floating.
4 NC unconnected No internal connection. May be left floating or tied to any convenient net; no electrical function.
5 VOUT power_out Regulated 3.3 V output (fixed for the -3302 option), up to 300 mA maximum output current with ~200 mV typ dropout at 100 mA. Requires >=1 µF ceramic/tantalum/aluminum electrolytic output capacitor for stability.
