TS9005 600mA CMOS LDO with Enable Function SOT-25 Pin Definition: 1. Input 2. Ground 3. Enable 4. Bypass 5. Output 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 350mV. 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 50µA. 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.

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. 3/5 Version: C07 TS9005 600mA CMOS LDO with Enable Function SOT-25 Mechanical Drawing Unit: Millimeters Marking Diagram F = Device Code x = Voltage Code k=1.8V, s=3.3V Y = Year Code (3=2013, 4=2014……) W = Week Code WW: 01~26 (A~Z) 27~52 (a~z) X = Internal ID Code 4/5 Version: C07 TS9005 600mA CMOS LDO with Enable Function Notice Specifications of the products displayed herein are subject to change without notice.
