LTC1844ES5-SD#TRPBF

Analog Devices · Linear Voltage Regulators (LDO) · TSOT-23-5

LTC1844ES5-SD#TRPBF from Analog Devices, 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 IN power_in Power input for the regulator and load; the datasheet specifies VIN from 1.6V to 6.5V, absolute supply voltage of -7V to 7V, and the pin withstands reverse voltages, so a 0.1µF to 1µF bypass to ground is usually sufficient.
2 GND power_in Ground and heat sink; solder to a ground plane or large pad to maximize heat dissipation.
3 SHDN input Active-low shutdown input with a 0.35V to 0.9V threshold (0.65V typical) and typically less than 10nA pin current; it cannot be left floating and must be tied to the input pin if not used.
4 ADJ input Error amplifier input for the adjustable output, referenced to 1.25V with about 30nA bias current flowing into the pin, setting an output range of 1.25V to 6V through an external resistor divider from OUT to GND.
5 OUT power_out Voltage regulated output that supplies the load; a minimum 1µF output capacitor is required to ensure stability.
