STMicroelectronics LDS3985
The LDS3985 provides up to 300 mA, from 2.5 V Very low dropout voltage (150 mV typ. It is stable with ceramic and 300 mA load, 0.4 mV typ. The ultra low Very low quiescent current (85 µA typ.FEATURES
● Input voltage from 2.5 V to 6 VDESCRIPTION
● Stable with low ESR ceramic capacitors The LDS3985 provides up to 300 mA, from 2.5 V● Very low dropout voltage (150 mV typ. at to 6 V input voltage. at 1 mA load) high quality tantalum capacitor. The ultra low
● Very low quiescent current (85 µA typ. at no load, 200 µA typ. at 300 mA load; max. 1.5 µA in OFF mode)
● Guaranteed output current up to 300 mA
● Wide range of output voltages available on request: fixed from 1.25 V to 5 V with 100 mV step
● Fast turn-on time: typ. 240 µs [CO = 2.2 µF, CBYP = 33 nF and IO = 1 mA] drop voltage, low quiescent current and low noise make it suitable for low power applications and battery-powered systems. Shutdown logic control function is available, this means that when the device is used as local regulator, it is possible to put a part of the board in standby, decreasing the total power consumption. Typical applications are mobile phones and similar battery-powered wireless systems, portable information appliances.
