Unitrode UC1836
The UC1835/6 families of linear controllers are optimized for the design of low cost, low dropout, linear regulators. These devices contain a high gain error amplifier, a 250mA output driver, and a precision reference. These devices are available in fixed, 5V, (UC1835), or adjustable, (UC1836), versions.| Part No. | UC1836 |

DESCRIPTION
Using an external pass element, dropout voltages of less than 0.5V are readily obtained. In addition, current sense with foldback provides for a 2.5A peak output current dropping to less than 0.5A at short circuit. In the fixed 5 volt version, the only external parts required are an external pass element, an output capacitor, and a compensation capacitor. On the adjustable version the output voltage can be set anywhere from 2.5V to 35V with two external resistors. Additional features of these devices include under-voltage lockout for predictable start-up, thermal shutdown and short circuit current limiting to protect the driver device.
