EZ55Z3L 0.25 Amp Positive Voltage Regulators POWER MANAGEMENT Description Features u u u u u u u The EZ55Z3L voltage regulators are monolithic integrated circuits designed for use in applications requiring a well regulated positive output voltage with low input-tooutput 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. External capacitor not required for stability Low dropout performance Five fixed voltage options: 3.3V, 5V, 9V, 12V, 24V Adjustable output down to 1.25V Line regulation typically 0.015% Load regulation typically 0.1% TO-92 and SOT-223 packages Typical Application Circuits Fixed Voltage Regulator Adjustable Voltage Regulator R1 VOUT = 1.250 • 1 + R 2 Revision 2, January 2001 1 www.semtech.com EZ55Z3L POWER MANAGEMENT Absolute Maximum Ratings Parameter Sy mbol Maximum U nits Operati ng Input Voltage VIN VOUT + 10 V Power D i ssi pati on(1) PD 2.5 W Thermal Resi stance Juncti on to Ambi ent SOT-223 TO-92 q JA 62.3 132 °C /W Thermal Resi stance Juncti on to C ase SOT-223 TO-92 q JC 15 66 °C /W Operati ng Juncti on Temperature Range TJ 0 to 125 °C Storage Temperature Range TSTG -65 to 150 °C Lead Temperature (Solderi ng) 10 Sec.
