TPS72501DCQR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS72501DCQR from Texas Instruments, in a SOT-223-6. 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 FB input For the TPS72501 adjustable version this pin (labeled RESET/FB on the generic DCQ pin diagram) is the feedback input that senses the externally divided output voltage against the internal 1.22-V bandgap reference; allowed voltage range is -0.3 V to VI + 0.3 V and feedback bias current is typically ±100 nA (TPS72501 replaces the RESET function with FB on this package pin, per the datasheet note).
2 OUT power_out Regulated output voltage pin, rated for 0 to 1-A continuous output current over -40°C to 125°C junction temperature; stable with any output capacitor, with a 10-µF capacitor recommended for improved transient response and noise performance.
3 GND power_in Ground/common reference pin for the device.
4 IN power_in Input supply voltage pin, recommended operating range 1.8 V to 6 V (absolute maximum -0.3 V to 7 V); a 1-µF or larger ceramic bypass capacitor to GND close to the device is required for stability.
5 ENABLE input Enable input; logic high (VIH ≥ 1.3 V) turns the regulator on and logic low (VIL ≤ 0.4 V) forces standby mode with less than 1-µA supply current; allowed voltage range is -0.3 V to VI + 0.3 V.
6 GND (tab) power_in Package thermal tab, internally tied to GND, used for heat dissipation to the PCB copper area; the datasheet states the tab is GND for the SOT-223 (and DDPAK) packages.
