PJ1117
1 Amp Low Dropout Positive Voltage Regulator
|
he PJ1117 Series of high performance positive voltage |
|
|
|
|
|
|
|
|
|
|
||
|
regulators are designed for use in applications requiring |
TO-220 |
|
|
TO-263 |
|
Tlow dropout performance at full rated |
current, |
|
|
|||
|
|
|
|
|||
Additionally, the PJ1117 Series provides excellent regulation |
|
|
|
|
||
over variations due to changes in line, load and temperature. |
|
|
|
|
||
Outstanding features include low dropout performance at |
|
|
|
|
||
rated current, fast transient response. The PJ1117 Series are |
|
|
|
|
||
three terminal regulators with fixed and adjustable |
voltage |
