TPS77516PWPR

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

TPS77516PWPR 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 GND power_in Ground reference; the datasheet lists nine GND pins (1, 2, 3, 9, 10, 11, 12, 19, 20) that are all to be tied to ground.
2 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
3 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
4 NC unconnected No internal connection.
5 EN input Negative polarity enable input; applying a TTL high signal shuts down the regulator, and EN should be tied to ground if shutdown is not used.
6 IN power_in Input voltage; the absolute maximum input voltage range is -0.3 to +13.5 V.
7 IN power_in Input voltage; the absolute maximum input voltage range is -0.3 to +13.5 V.
8 NC unconnected No internal connection.
9 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
10 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
11 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
12 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
13 OUT power_out Regulated output voltage; the output voltage at OUT is rated to a maximum of 7 V and output current is internally limited to approximately 1.7 A.
14 OUT power_out Regulated output voltage; the output voltage at OUT is rated to a maximum of 7 V and output current is internally limited to approximately 1.7 A.
15 FB/NC unconnected Feedback input for adjustable versions only; not internally connected on fixed-output versions such as the TPS77516.
16 RESET output Open-drain RESET output on TPS775xx devices, which pulls low when the output drops to between 92% and 98% of its nominal value and requires an external pullup if used.
17 NC unconnected No internal connection.
18 NC unconnected No internal connection.
19 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
20 GND power_in Ground reference; one of nine GND pins that are all to be tied to ground.
21 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
