6A Adjustable, and Fixed 3.3V
and 5V Linear Regulators
Description
Features
The CS5206 -X series of linear regu-
lators provides 6A at adjustable
and fixed voltages of 3.3V and 5V
with an accuracy of ±1% and ±2%
respectively. The adjustable version
uses two external resistors to set
the output voltage within a 1.25V
to 13V range.
The regulators are intended for use
as post regulators and microproces-
sor supplies. The fast loop response
and low dropout voltage make
these regulators ideal for applica-
tions where low voltage operation
and good transient response are
important.
The circuit is designed to operate
with dropout voltages as low as 1V
depending on the output current
level. The maximum quiescent cur-
rent is only 10mA at full load.
The regulators are fully protected
against overload conditions with
protection circuitry for Safe
Operating Area (SOA), overcurrent
and thermal shutdown.
The regulators are available in TO-
220 and surface mount D2 packages.

Applications Information
The CS5206 -X family of linear regulators provide fixed or
adjustable voltages at currents up to 6A. The regulators
are protected against short circuit, and include thermal
shutdown and safe area protection (SOA) circuitry. The
SOA protection circuitry decreases the maximum avail-
able output current as the input-output differential volt-
age increases.
The CS5206 -X has a composite PNP-NPN output transistor
and requires an output capacitor for stability. A detailed
procedure for selecting this capacitor is included in the
Stability Considerations section.
The output voltage is set according to the formula:
( )VOUT = VREF ´ R1 + R2 + IAdj ´ R2
R1
The term IAdj ´ R2 represents the error added by the adjust
pin current.
R1 is chosen so that the minimum load current is at least
10mA. R1 and R2 should be the same type, e.g. metal film
for best tracking over temperature. The adjust pin is
bypassed to improve the transient response and ripple
rejection of the regulator.
Adjustable Operation
The adjustable regulator (CS5206 -1) has an output voltage
range of 1.25V to 13V. An external resistor divider sets the
output voltage as shown in Figure 1. The regulator main-
tains a fixed 1.25V (typical) reference between the output
pin and the adjust pin.
A resistor divider network R1 and R2 causes a fixed cur-
rent to flow to ground. This current creates a voltage
across R2 that adds to the 1.25V across R1 and sets the
overall output voltage. The adjust pin current (typically
50µA) also flows through R2 and adds a small error that
should be taken into account if precise adjustment of VOUT
is necessary.
