ICW1232A33PGQ1

The ICW1232-Q1 series is a 1.4uA IQ, high-precision, high-PSRR, low-dropout linear regulator manufactured using CMOS process. The ICW1232-Q1 series regulators integrate a fixed voltage reference, thermal protection, current limiting circuit, phase compensation circuit, and a low on-resistance MOSFET, achieving ultra-low power consumption, high ripple rejection, and low dropout performance. The ICW1232-Q1 series is compatible with ceramic capacitors that are smaller in size than tantalum capacitors, and does not require bypass capacitors, enabling further space savings. The high-speed transient response of the ICW1232-Q1 series handles load current fluctuations effectively, making it particularly suitable for handheld and RF applications. The output can be disabled via the CE pin on the chip, with quiescent current reduced to 0uA in shutdown mode. The ICW1232-Q1 is a high-performance LDO regulator for automotive applications, with the entire product line certified to the AEC-Q100 standard.
