TPS73601QDBVRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS73601QDBVRQ1 from Texas Instruments, 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 IN power_in Unregulated supply input, 1.7 V to 5.5 V operating range (absolute max -0.3 V to 6.0 V). Feeds the internal NMOS pass element via a 4 MHz charge pump. An input bypass capacitor is optional but recommended for noisy supplies.
2 GND power_in Device ground reference. Ground pin current is nearly constant over all output-current conditions (typ 400 uA at 10 mA, 800 uA at 400 mA). Shutdown current is under 1 uA typ.
3 EN input Active-high enable input. Drive >=1.7 V (VEN(HI)) to turn the regulator on; drive <=0.5 V (VEN(LO)) to place the device in shutdown (IGND ~0.02 uA typ). Must not be left floating; tie to IN if always-on operation is desired. Absolute max -0.3 V to 6.0 V.
4 NR/FB input Dual-function pin. On the TPS73601 (adjustable) it is the FB feedback input from the external R1/R2 divider that sets VOUT = (R1+R2)/R2 x 1.204 V (internal reference 1.20 V typ, FB pin current 0.1 uA typ). On the fixed-voltage TPS73625/TPS73633, this pin is NR: an optional noise-reduction capacitor to GND (typ 0.01 uF) that lowers output noise to ~8.5 x VOUT uVRMS. Absolute max -0.3 V to 6.0 V.
5 OUT power_out Regulated output, 1.20 V to 5.5 V programmable via FB divider on TPS73601. Delivers up to 400 mA with 75 mV typ dropout and internal current limit of 650 mA typ (foldback to 450 mA typ short-circuit). Output capacitor is optional (stable with 0-10 uF); use 0.1-10 uF for best transient response. Absolute max -0.3 V to 5.5 V.
