TPS7A2028PDBVR

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

TPS7A2028PDBVR from Texas Instruments, 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 IN power_in Input voltage supply (1.6V to 6.0V) with minimum 0.47μF capacitor to GND for optimal transient response and minimized input impedance.
2 GND power_in Common ground reference; connect to ground plane for best thermal performance.
3 EN input Enable input with 500kΩ internal pulldown; high voltage (>VEN(HI)) enables regulator output, low voltage (<VEN(LOW)) disables regulator and discharges output to GND.
4 N/C unconnected No internal electrical connection; leave floating or do not connect to any potential.
5 OUT output Regulated output voltage (0.8V to 5.5V) requiring 0.47μF to 200μF low-ESR capacitor to GND for stability; internal 150Ω pulldown prevents charge remaining when regulator disabled.
