R1172N331D-TR-FE

Nisshinbo Micro Devices Inc · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

R1172N331D-TR-FE from Nisshinbo Micro Devices Inc, in a SOT-23-5. 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 Voltage regulator output pin; the absolute maximum output voltage is −0.3 V to VIN+0.3 V.
2 GND power_in Ground pin.
3 VDD power_in Input pin; the input voltage range is 1.4 V to 6.0 V, with an absolute maximum input voltage of 6.5 V.
4 NC unconnected No connection.
5 CE input Chip enable pin; for the D option ("H" active with auto discharge) it is active high, with VCEH minimum 1.0 V and VCEL maximum 0.4 V, and an absolute input range of −0.3 V to 6.5 V.
