MAX603ESA+T

Analog Devices Inc Maxim Integrated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

MAX603ESA+T from Analog Devices Inc Maxim Integrated, in a SOIC-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 IN power_in Regulator Input. Supply voltage can range from 2.7V to 11.5V. Bypass with 0.1µF to 10µF capacitor.
2 GND power_in Ground. These pins function as heatsinks in the SOIC package. All GND pins must be soldered to the circuit board for proper power dissipation. Connect to large copper pads or planes to channel heat from the IC.
3 GND power_in Ground. These pins function as heatsinks in the SOIC package. All GND pins must be soldered to the circuit board for proper power dissipation. Connect to large copper pads or planes to channel heat from the IC.
4 OFF input Shutdown, active low. A low input on OFF puts the regulator in 2µA shutdown mode. Switch logic levels in less than 1µs with the high level above the OFF threshold (typically ≥4V when VIN=11.5V). Connect to IN for normal operation.
5 SET input Feedback for Setting the Output Voltage (Dual-Mode). Connect to GND to select the preset internal 5V (MAX603) output. Connect to an external resistor divider from OUT for adjustable output between 1.25V and 11V (VOUT = VSET × (1 + R1/R2), VSET = 1.20V).
6 GND power_in Ground. These pins function as heatsinks in the SOIC package. All GND pins must be soldered to the circuit board for proper power dissipation. Connect to large copper pads or planes to channel heat from the IC.
7 GND power_in Ground. These pins function as heatsinks in the SOIC package. All GND pins must be soldered to the circuit board for proper power dissipation. Connect to large copper pads or planes to channel heat from the IC.
8 OUT power_out Regulator Output. Fixed 5V (MAX603) or adjustable from 1.25V to 11.0V. Sources up to 500mA for input voltages above 4V. Bypass with 10µF capacitor for stability (do not use less than 3.3µF).
