AIC1704B

35Vin 250mA Io Ultralow-Quiescent-Current LDO in SOT89

FEATURES
  • Output Current of 250mA
  • Ultra Low Quiescent Current (Iq ? 15 μA for IOUT = 1mA)
  • Dropout Voltage Typically 300mV at IOUT = 50mA
  • Internal Thermal Overload Protection
  • Internal Short-Circuit Current Limit
  • Excellent Line Regulation (<6mV)
  • Ceramic Capacitor Stable
APPLICATIONS
  • E-meters, Water Meters and Gas Meters
  • Fire Alarm, Smoke Detector
  • Appliances and White Goods
DESCRIPTION
The AIC1704B ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 15μA quiescent current at a 1mA load, the AIC1704B 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 AIC1704B 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 AIC1704B has a 35V maximum operating voltage limit, a -40°C to 85°C operating temperature range, and ±3% output voltage tolerance over the entire output current, input voltage and temperature range. The AIC1704B is available in a SOT223-3 and SOT89-3 surface mount packages.
