TPS73201QDRBRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SON-8-EP(3x3)

TPS73201QDRBRQ1 from Texas Instruments, in a SON-8-EP(3x3). 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 OUT output Regulator output, stable with no external output capacitor; the output has no active pulldown during overvoltage.
2 NC unconnected No internal connection.
3 FB input Input to the control-loop error amplifier that sets the output voltage; FB pin current is 0.1 µA typical and 0.45 µA maximum for TPS73201-Q1.
4 GND power_in Ground connection for the regulator.
5 EN input Enable input: driving it high turns the regulator on, and driving it below 0.5 V (maximum) puts the regulator in shutdown; if unused, connect it to IN.
6 NC unconnected No internal connection.
7 NC unconnected No internal connection.
8 IN power_in Unregulated input supply, specified from 1.7 V to 5.5 V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
