GM7333

GM7333 40V 250mA Ultralow-Quiescent-Current LDO 40V 250mA Ultralow-Quiescent-Current LDO General Description The GM7333 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 1.5μA quiescent current at no load, the GM7333 is ideally suited for standby micro-control-unit systems, especially for always-on applications like E-meters, fire alarms, smoke detectors and other battery operated systems. The GM7333 retains all of the features that are common to low dropout regulators including a low dropout PMOS pass device, short circuit protection, and thermal shutdown. The GM7333 has a 40-V maximum operating voltage limit, a -40°C to 125°C operating temperature range, and ±2% output voltage tolerance over the entire output current, input voltage, and temperature range. The GM7333 is available in a SOT893 through-hole and SOT235, surface mount packages.
