WWW.Microsemi .COM LX8213 LX8213 PRODUCTION DATASHEET LX8213 300mA Low Noise CMOS LDO Regulator TM DESCRIPTION KEY FEATURES The LX8213 LDO regulator is part of The LX8213 also exhibits low output 2.5V to 6V Wide Input Voltage Microsemis family of positive voltage noise with only 60uV over a 100kHz Range RMS regulator ICs using CMOS technology. The bandwidth. Power supply rejection exceeds Fixed Output at 1.2V or 3.3V device provides a compact and cost effective 65dB at 100Hz. Adjustable Output Voltage Range solution featuring low power consumption Other features of LX8213 include an from 1.2V to 5.5V over a wide supply voltage range, high output active low shutdown input with a 3M Low Quiescent Current of Typical voltage accuracy, low dropout, excellent line internal pull-down for low cost power 60uA and load regulation, fast transient response, sequencing, internal soft-start circuitry to Low Dropout Voltage of Typical and low noise. prevent inrush current, short circuit current 170mV at 3.3V 300mA The LX8213 operates over a wide input limit, and thermal overload protection. Stable with Low ESR 1uF voltage range of 2.5V to 6V, and consumes The LX8213 operates over -40C to Input/Output Bypass Ceramic only 60uA typical quiescent current at no load +85C ambient temperature range and is Capacitors and a low 0.1uA shutdown current. Output available in a tiny 5 pin SOT-23 ROHS Ultra Low Shutdown Current of voltage options include fixed 1.2V, 3.3V, or compliant package. Typical 0.1uA an adjustable output voltage which may be Low Output Noise of Typical set from 1.2V to 5.5V. The LDO delivers up 60uV at VOUT=1.2V RMS to 300mA of output current, with a foldback Fast Transient Response current limit of approximately 400mA. At Shutdown Control Input 300mA load, dropout voltage measures only Foldback Current Limit 170mV for a 3.3V output. 50mA Short Circuit Limit Tight load and line regulation is achieved Over Temperature Protection over the full output current and supply range. Standard Package SOT-23 The high bandwidth control loop provides fast RoHS Compliant transient response to reduce output voltage APPLICATIONS deviation using low cost external ceramic capacitors in the 1uF range.
