natlinear LN1234
The LN1234 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.| Part No. | LN1234 |

GENERAL DESCRIPTION
Output voltage is selectable in 50mV increments within a range of 0.85V ~ 1.8V. 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.●
