NCP729
200 mA Ultra-Low Noise
Very-Low Iq, High PSRR,
LDO Linear Voltage
Regulator
The NCP729 is a 200 mA LDO suitable to provide clean analog
power supply rails for noise sensitive applications. This device
features Ultra−Low Noise performance, High Power Supply Rejection
Ratio and Very good transient response characteristics. Very Low
Dropout and Very Low Quiescent Current makes this LDO an
attractive choice for wide range of battery powered, portable products.
Current Limit and Thermal Shutdown provide protection during
failure conditions. NCP729 is available in 1.06 mm x 1.06 mm Chip
Scale Package and it is stable with small 1
mF
Ceramic capacitors.
