General Description
TS5215 is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically 17mV at
light loads and 300mV at 300mA), and very low power consumption (125uA at 100uA), providing high output current
even when the application requires very low dropout voltage. The Chip Enable (EN) includes a CMOS or TTL
compatible input allows the output to be turned off to prolong battery life. When shutdown, power consumption drops
nearly to zero.
TS5215 is included a precision voltage reference, error correction circuit, a current limited output driver, over
temperature shutdown, revered battery protection and a reference bypass pin to improve its already excellent low-
noise performance.

... C BYPASS No Load Stability The TS5215 series will remain stable and in regulation with no load, unlike many other voltage regulators. This is especially important in CMOS RAM keep alive applications. Adjustable Regulator Design The adjustable regulator versions can be adjusted to a specific output voltage by using two external resistors to programming the output voltage anywhere between 1.25 and the 8V maximum operating rating of the family. Two resistors are used. Resistors can be quite large up to 470kΩ ...

... Thermal Characteristics TS5215 series is designed to provide 300mA (5V version) 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-ambient thermal resistance of the device and the ...
