HT7530-1 3V LDO Voltage Regulator IC – 100mA – SOT-89 – Holtek

The HT7530-1 from Holtek is a compact, low-dropout (LDO) 3V positive voltage regulator designed for low-power and battery-operated electronic applications. Packaged in a space-efficient SOT-89 3-pin surface-mount package, this regulator delivers a stable 3V output with a maximum load current of 100mA.

The device features an ultra-low quiescent current of only 2.5µA (typ.), making it an excellent choice for energy-efficient and long-battery-life designs. With a typical dropout voltage of just 100mV at 30mA, the HT7530-1 provides reliable regulation even when input voltage is just slightly above the output voltage.

Supporting input voltages up to 24V (and up to 30V for some variants), the regulator also includes short-circuit protection and thermal shutdown to ensure safe operation in demanding environments. Ideal for portable electronic devices, communication systems, instrumentation, and low-noise circuits.
