S52xxM
Low Drop Output Voltage Regulator
Description
The S52xxM is a u-cap 150mA linear voltage regulator in the SOT-25 package. This
regulator has very low dropout voltage and very low ground current. It is designed
especially for hand-sets, battery-powered devices and can be controlled by a CMOS or TTL.
When the S52xxM is disabled, power consumption drops to nearly zero.

S52xxM
Output Capacitor Selection
AUK strongly recommends the use of low ESR(Equivalent series resistance) ceramic
capacitors for Cout and CN . The S52xxM is stable with low ESR capacitor (as low as zero ).
The value of the output capacitor should be 1uF or higher. Either ceramic chip or a
tantalum capacitor may be used at the output. Use of ceramic chip capacitors offer
significant advantages over tantalum capacitors. A Ceramic capacitor is typically cheaper
than a tantalum capacitor, it usually has a smaller footprint, lower height, and lighter
weight than a tantalum capacitor. Furthermore, unlike tantalum capacitors which are
polarized and can be damaged if connected incorrectly, ceramic capacitors are non-
polarized. Low value ceramic chip capacitors with X5R or X7R dielectric are available in the
100pF to 4.7uF range. Beware of using ceramic capacitors with Y5V dielectric since their
ESR increases significantly at cold temperatures. Figure 9 shows a list of recommended
ceramic capacitors for use at the output of S52xxM.
If a tantalum output capacitor is used then for stable operation AUK recommends a low
ESR tantalum capacitor with maximum rated ESR at or below 0.4. Low ESR tantalum
capacitors, such as the TPS series from AVX Corporation (www.avxcorp.com) or the T495
series from Kemet (www.kemet.com) may be used.
In applications where a high output surge current can be expected, use a high value but
low ESR output capacitor for superior load transient response. The S52xxM is stable with
no load.
