The is a fixed voltage linear regulator that can output 9V at up to 1A current with an input voltage range of 11 — 35V. The 78xx series of fixed-voltage linear regulators are some of the most popular linear regulators available and have been around for a very long time.
They have built-in current limiting and over temperature protection and tend to be fairly robust devices. The prefix may vary depending on the mfr so you may see them listed as LM78xx, MC78xx, L78xx or just 78xx. The is a commonly used linear regulator. For basic operation, no external components are required.
Just hook up the input voltage and ground and you have 9V available on the output. The part ideally should be a low ESR part such as a Tantalum or Mylar capacitor, but small electrolytic caps generally work fine.
An output capacitor of 0. Linear regulators have less ripple on their outputs compared to DC-DC converters that can be used for the same basic purpose, but the trade-off is that the linear regulators also tend to dissipate more heat in the process. The reason is that the linear regulator uses a series pass transistor on its output to drop the excess voltage. The larger the voltage difference is between Vin and Vout, the higher the power dissipation will be which limits how much current can be drawn from the device.
The TO package will need to dissipate 3W of power. Under typical conditions, the device can dissipate about 1 — 1. As a general rule, you always want to use as low of an input voltage as possible to minimize power loss though the device and maximize the output current available.

Description Reviews 0 Description The is a fixed voltage linear regulator that can output 9V at up to 1A current with an input voltage range of 11 — 35V. Basic Operation The is a commonly used linear regulator.
Under high current loads or with large input to output voltage differentials, the device can get very hot, so use care when handling. Reviews There are no reviews yet. LM Adjustable Voltage Regulator 1.
