Description |
Features |
The EZ55Z3L voltage regulators are monolithic integrated circuits designed for use in applications requiring a well regulated positive output voltage with low input-to- output differential voltage requirements.
Outstanding features include full power usage up to 250mA of load current, internal current limiting and thermal shutdown. Safe area protection on the die is also included, providing protection of the series pass transistor under most operating conditions. TO-92 and SOT-223 packages are available for cost effective applications.
υExternal capacitor not required for stability
υLow dropout performance
υFive fixed voltage options: 3.3V, 5V, 9V, 12V, 24V
υAdjustable output down to 1.25V
υLine regulation typically 0.015%
υLoad regulation typically 0.1%
υTO-92 and SOT-223 packages
