TPS70145PWPR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · HTSSOP-20-EP

TPS70145PWPR from Texas Instruments, in a HTSSOP-20-EP. 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 NC unconnected No connection
2 VIN1 power_in Input voltage for regulator 1, rated -0.3 V to +7 V
3 VIN1 power_in Input voltage for regulator 1, rated -0.3 V to +7 V
4 MR1 input Manual reset input 1, active low with internal pull-up of 6 mA
5 MR2 input Manual reset input 2, active low with internal pull-up of 6 mA
6 EN input Active low enable input for device shutdown and enable control, rated -0.3 V to +7 V
7 SEQ input Power-up sequence control with internal pull-up of 6 mA, high or open causes VOUT2 to power up first, low causes VOUT1 first
8 GND power_in Ground
9 VIN2 power_in Input voltage for regulator 2, rated -0.3 V to +7 V
10 VIN2 power_in Input voltage for regulator 2, rated -0.3 V to +7 V
11 NC unconnected No connection
12 VOUT2 power_out Output voltage of regulator 2, supports maximum 250 mA output current
13 VOUT2 power_out Output voltage of regulator 2, supports maximum 250 mA output current
14 VSENSE2/FB2 input Regulator 2 output voltage sense or feedback terminal for adjustable configuration
15 RESET tri_state Open drain output, active low power-on reset signal with 120 ms delay, maximum voltage 7 V
16 PG1 tri_state Open drain output, goes low when VOUT1 voltage is less than 95% of the nominal regulated voltage, maximum voltage 7 V
17 VSENSE1/FB1 input Regulator 1 output voltage sense or feedback terminal for adjustable configuration
18 VOUT1 power_out Output voltage of regulator 1, supports maximum 500 mA output current
19 VOUT1 power_out Output voltage of regulator 1, supports maximum 500 mA output current
20 NC unconnected No connection
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
