iD9301
Low Noise 300mA LDO Regulator
Apr. 2011 1 Rev 0.8
General Description
The iD9301 is a 300mA with fixed output voltage
options ranging from 1.5V, low dropout and low noise
linear regulator with high ripple rejection ratio and fast
turn-on time.
It includes a reference voltage source, an error
amplifier, driver transistors and an internal current
limiter. The current limiter’s holdback circuit operates
as a short protection.
The iD9301 works well with low ESR ceramic
capacitors, suitable for portable RF and wireless
battery-powered applications with stringent space
requirements and demanding performance. It also
offers ultra low noise output and has low quiescent
current.
