GR7533H

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

GR7533H from GR, in a SOT-89-3. 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 GND power_in Chip ground terminal (芯片接地端); the datasheet gives no further electrical limit for this pin.
2 VIN power_in Input pin (启动输入端) for the regulator; maximum input voltage is 25 V per the GR7533H selection table, with an absolute maximum of 28 V.
3 VOUT power_out Regulated output (芯片输出端) at 3.3 V ±3% (3.201-3.399 V), sourcing at least 20 mA at VIN = 5.5 V with 1 mA load.

  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: gr7533h-etched.step / gr7533h-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr7533h.step / gr7533h.glb are the bare package body.
