LM29152RS

HTC Korea TAEJIN Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-5

LM29152RS from HTC Korea TAEJIN Tech, in a TO-252-5. 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 EN input Chip enable input. Logic high (VEN >= 2.4 V) turns the regulator on; logic low (VEN <= 0.8 V) puts the device in zero-current shutdown (IOUT typ 10 uA, max 500 uA at VIN <= 26 V). May be tied to VIN if ON/OFF control is not required. Absolute max VEN = -20 V to +60 V; recommended operating -/+26 V.
2 VIN power_in Input supply. Recommended operating range up to +26 V; absolute max -20 V to +60 V (60 V limited to <100 ms, <=1% duty). Bypass with an input capacitor (CIN) close to the pin.
3 GND power_in Device ground / return. Ground pin current is typ 8 mA at IO = 750 mA and typ 22 mA at IO = 1.5 A (max 20 mA at 750 mA per data). Also serves as the thermal reference for the exposed tab.
4 VOUT power_out Regulated output. Delivers up to 1.5 A with 350 mV (typ) full-load dropout. On the adjustable LM29152 the output voltage is set by an external divider: VOUT = VREF x (1 + R1/R2), VREF = 1.24 V typ (1.215 - 1.265 V). Current limit typ 2.1 A (max 3.5 A). Requires an output capacitor (COUT) for stability.
5 ADJ input Adjust pin for the LM29152 adjustable variant (this pin is labeled FLG/ADJ in the shared pinout table; on LM29152 it is the ADJ feedback input, on LM29151 it is the FLG error-flag open-drain output). Connect to the R1/R2 divider tap from VOUT to GND to program VOUT = 1.24 V x (1 + R1/R2). Adjust-pin bias current is typ 40 nA (max 80 nA).
