Product Brief
TLT807B0EPV
Linear voltage regulator for 24 V applications
Low dropout adjustable stand-by linear voltage regulator with overvoltage protection
The TLT807B0EPV is a 70 mA low dropout linear voltage regulator with enable feature.
The 70 mA regulator has an adjustable output voltage and is available in a TSDSO-14
package.
The wide input voltage range and the low quiescent current make it perfectly suitable
for supply systems connected permanently to the battery. The overvoltage protection
feature allows for the device to be used in 24 V automotive applications (e.g. trucks,
commercial vehicles etc.). With a 58 V load dump capability the device is perfectly suited
to supply loads in stand-by mode in 24 V applications.
The TLT807B0EPV has an integrated enable function and can be switched on and off via
the enable pin. The current consumption in OFF mode is limited to 1.5 µA. The device is
stable with a small 1 µF output capacitor.
The device also includes internal protection features such as output current limitation
and overtemperature shutdown.
