TPS7B6833QPWPRQ1

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · HTSSOP-28-EP

TPS7B6833QPWPRQ1 from Texas Instruments, in a HTSSOP-28-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 IN power_in Device input power-supply pin; unregulated input range is 4 V to 40 V recommended, with a absolute maximum of -0.3 V to 45 V.
2 NC unconnected No internal connection.
3 NC unconnected No internal connection.
4 EN input Device enable pin; pull low to disable the device and pull high to enable it, rated 0 V to VIN as a 40-V pin.
5 FSEL input Internal oscillator-frequency selection; pull low to select the high-frequency oscillator and pull high to select the low-frequency oscillator, rated 0 V to VIN as a 40-V pin.
6 WTS input Watchdog type selection; connect to GND for the window watchdog or pull high for the standard watchdog, rated 0 V to VIN as a 40-V pin.
7 NC unconnected No internal connection.
8 GND power_in Ground reference.
9 NC unconnected No internal connection.
10 NC unconnected No internal connection.
11 ROSC output Watchdog timer adjustment; a resistor from ROSC to GND sets the watchdog duration, and leaving it open or grounded makes the watchdog report a fault at WDO; rated 0 V to 5.5 V.
12 DELAY output Power-good delay-period adjustment; connect a capacitor to ground to set the power-good delay time; rated 0 V to 5.5 V.
13 WD input Watchdog service-signal input; rated 0 V to 5.5 V.
14 NC unconnected No internal connection.
15 WDO output Watchdog status output, open-drain; pull up to OUT or a reference through a resistor and it is pulled low on a watchdog fault; rated 0 V to 5.5 V.
16 WD_EN input Watchdog enable; pull low to enable the watchdog and pull high to disable it; rated 0 V to 5.5 V.
17 NC unconnected No internal connection.
18 WRS input Window ratio selection (window watchdog only); low sets open:closed ratio to 1:1 and high sets it to 8:1; rated 0 V to 5.5 V.
19 NC unconnected No internal connection.
20 NC unconnected No internal connection.
21 GND power_in Ground reference.
22 NC unconnected No internal connection.
23 NC unconnected No internal connection.
24 PG output Power-good output, open-drain; pull up to VOUT or a reference through a resistor and it is pulled low to ground when the output is not ready; rated 0 V to 5.5 V.
25 PGADJ output Power-good threshold adjustment; a resistor divider between PGADJ and OUT sets the threshold, and tying it to ground sets the threshold to 91.6% of VOUT; rated 0 V to 5.5 V.
26 NC unconnected No internal connection.
27 NC unconnected No internal connection.
28 OUT power_out Regulated 3.3-V or 5-V output; rated 0 V to 5.5 V in the recommended operating conditions, with output current up to 500 mA.
29 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
