NJM2895/96
2ch LOW DROPOUT VOLTAGE REGULATOR
! GENERAL DESCRIPTION
The NJM2895/96 is a 2ch low dropout voltage regulator with
ON/OFF control.
Advanced Bipolar technology achieves low noise, high ripple
rejection and low quiescent current.

State of control terminal:
•“H”→ output is enabled.
•“L” or “open” → output is disabled.
%In the case of using a resistance "R" between VIN and control.
The current flow into the control terminal while the IC is ON state (ICONT) can be reduced when a pull up resistance
"R" is inserted between VIN and the control terminal.
The minimum control voltage for ON state (VCONT (ON)) is increased due to the voltage drop caused by ICONT and the
resistance "R". The ICONT is temperature dependence as shown in the "Control Current vs. Temperature"
characteristics. Therefore, the resistance "R" should be carefully selected to ensure the control voltage exceeds the
VCONT (ON) over the required temperature range.
