LOW DROPOUT
VOLTAGE REGULATOR
NO. EA-038-111027
RN5RT SERIES
OUTLINE
The RN5RT Series are CMOS-based voltage regulator ICs with high output voltage accuracy and low supply cur-
rent developed . Each of these voltage regulator ICs consists of a voltage reference unit, an error amplifier, output
voltage setting resistors and a current limit circuit.
The output voltage of these ICs is fixed with high accuracy.
The built-in Driver Transistor of low ON Resistance permits developing of low dropout CMOS type regulator as
RN5RT Series.
Even if VOUT is shorted to GND, the current limit circuit protects the ICs from destruction.
Furthermore, these ICs have a chip enable function, so that the supply current on standby can be minimized.
Since the package for these ICs is the SOT-23-5 (Mini-mold) package, high density mounting of the ICs on
boards is possible.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under
any conditions. Moreover, such values for any two items must not be reached simultaneously. Operation
above these absolute maximum ratings may cause degradation or permanent damage to the device. These
are stress ratings only and do not necessarily imply functional operation below these limits.

In these ICs, the output voltage VOUT is detected by feed-back registers R1, R2, and the detected output voltage
is compared with a reference voltage by the error amplifier, so that a constant voltage is output.
A current limit circuit working for short protection and a chip enable circuit for standby function are included.

In the RN5RT Series, a constant voltage can be obtained without using capacitor C1 and C2. However, when the
wire connected to VIN is long, use a capacitor C1. Transient noise of output voltage occurred due to load deviation
can be reduced by using a capacitor C2.
Insert capacitors C1 and C2 with the capacitance of 0.1µF to 2.0µF between input/output pins and GND pin with
minimum wiring.
