LN1152 High Speed Low Dropout Middle Current Voltage Regulators

LN1152   High Speed Low Dropout Middle Current Voltage Regulators
1、General Description
   The LN1152 series are highly precise, low noise, positive voltage LDO regulators manufactured using  CMOS processes. The series achieves high ripple  rejection and low dropout and consists of a standard  voltage source, an error correction, current limiter and a  phase compensation circuit plus a driver transistor. The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series.
The current limiter's feedback circuit also operates as a short protect for the output current limiter and the output pin The CE function enables the output to be turned off, resulting in greatly reduced power consumption.
