0.6V DUAL ADJUSTABLE PRECISION SHUNT REGULATOR
Description
Pin Assignments
The ZXRD060 is a 10-terminal adjustable dual shunt
regulator offering excellent temperature stability and output
handling capability. The ZXRD060 simplifies the design of
isolated low voltage DC-DC regulators. With its low 0.6V
FB pin, it can control the regulation of rails as low 0.6V. This
makes it ideal for state of the art microprocessor/DSP and
PLD core voltage POL converters.

The device open-collector output can operate from 0.2V to

Separating the input from the open collector output enables
the ZXRD060 to be used to make low-cost low drop-out
regulators operating at low input voltages.

The ZXRD060 is available in two grades with initial
tolerances of 0.5% and 1% for the A and standard grades
respectively. It is available in the space saving low profile
10 pin DFN2626P10 package.

Function Block Diagram
The ZXRD060 differs from most other shunt regulators in that it has separate input and output pins and a low voltage
reference. This enables it to regulate rails down to 600mV and makes the part ideal for isolated power supply applications that
use opto-couplers in the feedback loop and where the open-collector output is required to operate down to voltages as low as
200mV.
The wide input voltage range of 2V to 18V and output voltage range of 0.2V to 18V enables the ZXRD060 to be powered from
an auxiliary rail, while controlling a master rail which is above the auxiliary rail voltage, or below the minimum VIN voltage. This
allows it to operate as a low-dropout voltage regulator for microprocessor/DSP/PLD cores.
As with other shunt regulators (and shunt references), the ZXRD060 compares its internal amplifier FB pin to a high accuracy
internal reference; if FB is below the reference then OUT turns off, but if FB is above the reference then OUT sinks current –
up to a maximum of 15mA.

Applications Information
The following show some typical application examples for the ZXRD060. It is recommended to include the compensation
capacitor C2 to guarantee stability. C2 may range in value from 0.1µF to 10µF depending on the application. The time constant
formed by C2 and R3 should be greater than 1ms multiplied by the feedback factor R2/(R1 + R2).
Both C1 and C2 should be as close to the ZXRD060 as possible and connected to it with the shortest possible track. In the
case of fig 9 and fig10, it means the opto-coupler will have to be carefully positioned to enable this.
