DS8201-33F8

DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · ESOP-8

DS8201-33F8 from DSTECH, in a ESOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated 3.3V power output (±1% accuracy, up to 80mA). Requires a 1µF to 22µF output capacitor placed close to VOUT and GND for stability and improved PSRR/transient response.
2 SNS input Output voltage sense input; tie to VOUT for fixed 3.3V operation, or connect to a resistor divider from VOUT to GND for adjustable output. Abs-max on the -33 option is -0.3V to 6V; typical SNS input current ~0.85µA.
3 NC unconnected No internal connection; leave floating.
4 GND power_in Device ground reference. Should be tied to the exposed pad and to the ground planes with short, wide traces near input/output capacitors for best performance.
5 EN input Active-high enable input. VIH ≥ 3.0V enables regulation; VIL ≤ 0.6V drives shutdown mode (ISD ≈ 100nA typical, 500nA max). EN input current ~10nA (VEN = 36V).
6 NC unconnected No internal connection; leave floating.
7 NC unconnected No internal connection; leave floating.
8 VIN power_in High-voltage supply input, 3.0V to 110V recommended (abs-max 125V to GND). Requires a 1µF or larger input capacitor placed close to VIN and GND.
9 EP passive Exposed thermal pad on the ESOP-8 package. May be left floating or connected to GND; connecting to a copper ground pour is recommended to reduce θJA (55°C/W) and improve power dissipation (PD_max ≈ 1.82W at TA=25°C).
