Shutdown (SHDN)

The regulator can be shutdown by applying a voltage of >1.2V to the SHDN Pin. The regulator will

restart when the SHDN Pin is pulled below the shutdown threshold of 0.8V. If the remote shutdown

feature is not required, the SHDN Pin should be connected to GND.

Input Capacitance

Input bypass capacitors: Two (0.1µF and 1µF) ceramics and two 100µF low ESR tantalums (AVX

TPS or equivalent), placed very close to the V

Pin are required for proper operation. When the

input voltage supply capacitance is more than 4 inches from the device, additional input

capacitance is recommended. Larger input capacitor values will improve ripple rejection further

improving the integrity of the output voltage.

Output Capacitance

Output bypass capacitors: Two (0.1µF and 1µF) ceramics and two 100µF low ESR tantalums

(AVX TPS or equivalent)

are required for loop stability. Faster transient performance can be

achieved with multiple additional 1µF ceramic capacitors. Ceramic capacitors greater than 1µF in

value are not recommended as they can cause stability issues.

Tantalum capacitor values larger than the suggested value are recommended to improve the

transient response under large load current changes. The upper capacitance value limit is

governed by the delayed over-current latch function of the regulator and

can be as much as

10,000µF without causing the device to latch-off during start-up.

General Layout Rules

Low impedance connections between the regulator output and load are essential. Solid power and

ground planes are highly recommended. In those cases where the board impedances are not kept

very small, oscillations can occur due to the effect of parasitic series resistance and inductance

on loop bandwidth and phase margin.

R1 must be directly conected to the

OUT

Pin using as short a trace as possible with the

connection inside the first bypass capacitor (see Fig. 2a). The trace from ADJ Pin to R1 should

be as short as possible.

Connect ceramic output capacitors directly across the V

OUT

and GND Pins with as wide a trace as

design rules allow (see Fig. 2a). Avoid the use of vias for these capacitors and avoid loops. Fig.2

shows the ceramic capacitors tied directly to the regulator output.

The input capacitors should be connected as close a possible to the V

Pin.
