DESCRIPTION

The SP6200/6201 is an efficient linear voltage regulator with ultra-low dropout voltage, ground
current and quiescent current. Designed especially for hand-held, battery-powered devices,
the SP6200/6201 includes a CMOS or TTL compatible enable/shutdown control pin. When
shutdown, power consumption drops nearly to zero. Regulator ground current increases only
slightly in dropout, further prolonging battery life.

The SP6200/6201 is available in fixed and adjustable output voltage versions in a small SOT­23-5 package.

Note 1. Exceeding the absolute maximum rating may damage the device.

thermal shutdown. The θJA of the SP6200/6201(all versions) is 220°C/W mounted on a PC board (see “Thermal
Considerations” section for further details)
Note 4. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 5. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range; from 0.1mA to 100mA, SP6200; from 0.1mA to 200mA, SP6201. Changes in output voltage
due to heating effects are covered by the thermal regulation specification.
Note 6. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its
nominal value measured at 1V differential.
Note 7. Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the
load current plus the ground pin current.
Note 8. Thermal regulation is defined as the change in output voltage at a time ”t” after a change in power dissipation is
applied, excluding load or line regulation effects. Specifications are for a 100mA load pulse at VIN = 7V for t = 10ms.

THEORY OF OPERATION

V

OUT

=1.25 (R2/R1 + 1)

Enable/Shutdown

Forcing EN (enable/shutdown) high (>2V)
enables the regulator. EN is compatible with
CMOS logic gates. If the enable/shutdown feature
is not required, connect EN (pin 3) to IN (supply
input, pin 1). See Figure 1.

Input Capacitor

A 1µF or greater capacitor should be placed from
IN to GND.

Output Capacitor

An output capacitor is required between OUT
and GND to prevent oscillation. The minimum
size of the output capacitor is 1.0µF. Larger
values improve the regulator's transient response.
The output capacitor value maybe increased
without limit. The output capacitor should have
an ESR (effective series resistance) of about 5Ω
or less and a resonant frequency above 1MHz.
At lower values of output current, less output
capacitance is required for output stability. The
capacitor can be reduced to 0.47µF for current
below 10mA or 0.33µF for currents below 1mA.

No-Load Stability

The SP6200/6201 will remain stable and in
regulation with no load (other than the internal
voltage divider) unlike many other voltage
regulators. This is especially important in CMOS
RAM keep-alive applications.

T

is the maximum junction temperature of

J(max)

the die, 125˚C, and TA is the ambient operating
temperature. θJA is layout dependent.

The actual power dissipation of the regulator
circuit can be determined using the equation:

P

D =

(V

in - Vout)Iout

Substituting P
operating conditions that are critical to the
application will give the maximum operating
conditions for regulator circuit. For example,
when operating the SP6201 3.3 at room
temperature with a maximum footprint layout,
the maximum input voltage for a set output
current can be determined as follows:

The junction-to-ambient thermal resistance for
the maximum footprint is 220˚C/W. The
maximum power dissipation must not be
exceeded for proper operation. Using the output
voltage of 3.3V and an output current of 200mA,
the maximum input voltage can be determined.

Therefore, a 3.3V application at 200mA of
output current can accept a maximum input
voltage of 5.6V in a SOT-23-5 package.

Adjustable Regulator Applications

The SP6200/6201 can be adjusted to a specific
output voltage by using two external resistors
(Figure 2). The resistors set the output voltage
based on the following equation:

for PD and solving for

D(max)

Thermal Considerations

The SP6200/6201 is designed to provide 100/
200mA of continuous current in a very small
package. Maximum power dissipation can be
calculated based on the output current and the
voltage drop across the part. To determine the
maximum power dissipation of the package, use
the junction-to-ambient thermal resistance of the
device and the following basic equation:

Resistor values are not critical because ADJ
(adjust) has a high input impedance, but for best
results use resistors of 470kΩ or less. A capacitor

Dual-Supply Operation

When used in dual supply systems where the
regulator load is returned to a negative supply,
the output voltage must be diode clamped to
ground.
