Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS79533DCQG4 from Texas Instruments, in a SOT-223-6. 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	EN	input	Enable input: driving it high turns the regulator on and driving it low puts it in shutdown; VEN(HI) is 1.7 V minimum for the old chip and 0.85×VIN minimum for the new chip, VEN(LOW) is 0.7 V maximum for the old chip and 0.425 V maximum for the new chip, and EN can be tied to IN if shutdown is not needed.
2	IN	power_in	Regulator input supply: 2.7 V to 5.5 V for the old chip and 2.7 V to 6.0 V for the new chip, with absolute maximum VIN of 6 V (old chip) and 6.5 V (new chip), and a 1 µF input capacitor required on the new chip.
3	GND	power_in	Regulator ground, which must be connected to the ground plane and to the bypass capacitor ground returns.
4	OUT	power_out	Regulated output: 1 µF minimum ceramic output capacitor is required for stability, with absolute maximum VOUT of -0.3 V to 6 V and output current limited internally to 500 mA operating current.
5	NR	passive	On the old chip this is the noise-reduction pin for fixed-voltage versions, where an external capacitor of no more than 0.1 µF bypasses the internal bandgap noise; on the new chip it is listed as N/C (no internal connection).
6	GND	power_in	Pin 6 is the SOT-223 tab, which is electrically grounded and should be soldered to a large copper ground area for thermal performance.
