TPS7101QP

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · PDIP-8

TPS7101QP from Texas Instruments, in a PDIP-8. 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 GND power_in Device ground reference; all datasheet voltage values are specified with respect to network terminal ground.
2 EN input Enable input: a high level (VIH min 2 V) shuts the regulator down and a low level (VIL max 0.5 V) enables it, with EN tied to ground when the shutdown feature is not used; absolute maximum input range for EN is -0.3 V to 11 V.
3 IN power_in Regulator input supply; recommended input voltage for the TPS7101Q is 2.5 V to 10 V and absolute maximum input range is -0.3 V to 11 V.
4 IN power_in Second regulator input pin, internally tied with pin 3 to the input supply; recommended input voltage 2.5 V to 10 V and absolute maximum -0.3 V to 11 V.
5 OUT power_out Regulated output; the device supplies up to 500 mA (absolute maximum output current 2 A) and needs an output capacitor of about 10 µF solid tantalum with ESR below 1.2 Ω for stability.
6 OUT power_out Second regulated output pin, internally tied with pin 5; same 0 mA to 500 mA output range and stability requirements apply.
7 FB input Feedback input of the adjustable TPS7101 (Vref 1.178 V typical) that sets the output via an external R1/R2 divider; large divider resistors should be avoided because leakage at FB introduces error.
8 PG output Open-drain power-good output that pulls low when the output falls to 92% to 98% of nominal and requires an external pullup resistor, or can be left floating if unused; absolute maximum input range for PG is -0.3 V to 11 V.
