General Description
The TS9005 is a low dropout, positive linear regulator with very low quiescent. It can supply 600mA output current
with low dropout about 500mV.The BP pin with a 10nF bypass capacitor can help reduce the output noise level. The
characteristics of low dropout voltage and less quiescent current make it good for some critical current application,
for example, some battery powered devices. The typical quiescent current is approximately 45µA. In the shutdown
mode, the maximum supply current is less than 1uA. The TS9005 regulator is able to operate with output capacitors
as small as 1uF for stability.

Application Information
TS9005 is specifically designed for portable applications requiring minimum board space and smallest components.
It can provide 600mA output current at dropout voltage about 600mV. Beside, current limit and thermal shutdown
features provide protection against any combination of overload or ambient temperature that could exceed junction
temperature.
Capacitor Selection
TS9005 is designed to be stable with a wide range of output capacitors. The ESR of the output capacitor affects
stability. Larger output capacitor value can decrease peak deviations and to improve transition response for larger
current changes. So the ESR of output capacitor is very important because it generates a zero to provide phase lead
for loop stability. There is no requirement for the ESR on the input capacitor, but voltage and temperature coefficient
have to be considered for device application environments.
The capacitor types (aluminum, ceramic and tantalum) have difference characterizations such as temperature and
voltage coefficients. All ceramic capacitors are produces with a variety of dielectrics, each with different behavior
across temperature and applications. Common dielectric use are X5R, X7R and Y5V. It is recommended to use 1uF
X5R or X7R dielectric ceramic capacitor with 30mΩ~50mΩ ESR range between device outputs to ground for transient
stability.
Current Limit and Thermal Shutdown Protection
In order to prevent overloading or thermal condition from damaging the device, TS9005 regulator has internal thermal
and current limiting functions designed to protect the device. It will rapidly shut off PMOS pass element during
overloading or over temperature condition.
