TS5215
300mA Low Noise LDO Voltage Regulator with Enable
Low Power Consumption
Low Drop Out Voltage 0.35V
Fixed and Adjustable Output
Enable Shutdown
General Description
The TS5215 series is an efficient linear voltage regulator with ultra low noise output, very low dropout voltage (typically
17mV at light loads and 350mV 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 (CE) 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.
The TS5215 series 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.
The TS5215 series is available in fixed and adjustable output voltage version in SOT-25, SOT-89-5L and SOP-8
package.

Pin Description
TTL/COMS compatible input. Logic high is
enable; logic low or open is shutdown
Unregulated input: +16V maximum supply
Ground: Ground pin and TAB/heatsink are
internally connected.
Regulator output
A 470uF capacitor (Cbypass) connected from
Bypass to Ground quiets this reference
Adjustment input: Feedback input. Connect to
resistive voltage-divider network. (Vout<8V)
