Description

The SE8119 series of high performance low dropout voltage regulators are designed for applications that require efficient conversion and fast transient response. A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage.

It does this by adjusting the output voltage so that it remains within a specified range.

This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.

Features

1. Low Dropout Performance.

2. Guaranteed 500mA Output Current.

3. Wide Input Supply Voltage Range.

4. Over-temperature and Over-current Protection.

5. Rugged 3KV ESD withstand capability

Pinouts:

Applications:

1. PC-Camera

2. Active SCSI Terminators.

3. High Efficiency Linear Regulators.

4. 5V to 3.3V Linear Regulators

5. Motherboard Clock Supplies

Description

The 7812CV, L7800 series of three-terminal positive regulators is available in TO-220 ISOWATT220 TO-3 and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications.These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
