3-MODE 150mA LDO REGULATOR
The R1162x Series consist of CMOS-based voltage regulator ICs with high output voltage
accuracy and low supply current. Each of these voltage regulator ICs consists of a voltage reference unit,
an error amplifier, resistors for setting output voltage, a current limit circuit, and so on. The output voltage
is internally fixed with high accuracy.
These ICs perform with the chip enable function and realize a standby mode with ultra low supply current. To prevent the
destruction by over current, the current limit circuit is included. The R1162x Series have 3-mode. One is standby mode with
CE or standby control pin. Other two modes are realized with ECO pin. Fast Transient Mode (FT mode) and Low Power
Mode (LP mode) are alternative with ECO pin. Consumption current is reduced at Low Power Mode compared with
Fast Transient Mode.
The output voltage is maintained between FT mode and LP mode.
Since the packages for these ICs are SOT-23-5 and
SON1612-6 packages, high density mounting of the ICs on boards is possible. |
