CAT6219-330TDGT3

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOT-23-5

CAT6219-330TDGT3 from onsemi, in a TSOT-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 VIN power_in Supply voltage input; operating range 2.3 V to 5.5 V (absolute max 6.5 V), with a 1 µF ceramic capacitor required to ground near the device.
2 GND power_in Ground reference; must be connected to the ground plane on the PCB.
3 EN input Active-high enable input with an internal 2.5 MΩ pull-down resistor so the output is disabled if left open; logic low below 0.4 V, high above 1.8 V.
4 BYP/ADJ passive On this fixed 3.3 V part it is the BYP pin, for an optional 10 nF bypass capacitor to GND that reduces output noise and improves high-frequency PSRR (ADJ on the adjustable version).
5 VOUT power_out LDO regulated output, up to 500 mA, requiring a 2.2 µF ceramic capacitor to ground (4.7 µF for better transient response), with a 250 Ω internal discharge switch.
