These • Low Input Voltage Requirement (Down to regulators can be used in a wide variety of 1.8 V) applications ranging from portable, battery-powered • Small Output Capacitor, 0.1-µF equipment to PC peripherals. The family features operation over a wide range of input voltages (1.8 V • Dropout Voltage Typically 200 mV at 150 mA to 5.5 V) and low dropout voltage (150 mV at full • Less Than 1 µA Quiescent Current in load). Therefore, compared to many other regulators Shutdown Mode that require 2.5-V or higher input voltages for • Thermal Protection operation, these regulators can be operated directly from two AAA batteries. Also, the typical quiescent • Over Current Limitation current (ground pin current) is low, starting at 85 µA • 5-Pin SOT-23 (DBV) Package during normal operation and 1 µA in shutdown mode. These regulators can be operated very efficiently and, in a battery-powered application, help extend the • Portable Communication Devices longevity of the device. • Battery Powered Equipment Similar LDO regulators require 1-µF or larger output • PCMCIA Cards capacitors for stability. However, this regulator uses an internal compensation scheme that stabilizes the • Personal Digital Assistants feedback loop over the full range of input voltages • Modems and load currents with output capacitances as low as • Bar Code Scanners 0.1-µF. Ceramic capacitors of this size are relatively • Backup Power Supplies inexpensive and available in small footprints. • SMPS Post Regulation This family of regulators is particularly suited as a • Internet Audio portable power supply solution due to its minimal board space requirement and 1.8-V minimum input voltage. Being able to use two off-the-shelf AAA batteries makes system design easier and also reduces component cost. Moreover, the solution will be more efficient than if a regulator with a higher input voltage is used.
