LDO ICs with fast transient response

Microsemi has released 300 mA capable low dropout voltage regulator IC for systems requiring low noise and fast transient response where abrupt load current changes are common. Few examples of such systems are set top boxes, digital televisions, broadband modems and wireless access points.

"System designers using Microsemi's LX8213 fast transient response ultra-low dropout regulator no longer need to bulk-up on capacitance, saving bill of materials cost and PCB area," said Richard Johnson, product line manager at Microsemi's Analog Mixed Signal Group

LX8213 key features:

Low dropout voltage of 170mV (typ) at 3.3V and 300mA
Input voltage range of 2.5V to 6V
Optimized for use with ceramic capacitors
Power saving mode
Fixed and adjustable output voltage options
Output discharges when disabled

Package: SOT-23
RoHS Compliant: Yes
Price: Each US$ 0.11 for 10K pieces
