EZ5Z3L

POWER MANAGEMENT Description The EZ5Z3L voltage converters are innovative two terminal devices that accept a regulated 5V input and reduce it to 3.3V over a range of 5mA to 250mA. The EZ5Z3L-ADJ is an adjustable three terminal version allowing output voltage trimming. The EZ5Z3L is available in SOT-223, TO-220 and TO-92 packages. 250mA 5V to 3.3V or Adjustable Output EZ DROPPER™ Features u u u u u u u u u u u u External components not required Heatsink not required 2 simple connections 250mA output current Generates no EMI or spikes Drops 5V to 3.3V, ADJ Industrial temperature range SOT-223, TO-220 and TO-92 packages EZ5Z3L Applications Cellular Telephones Instrumentation Peripheral Cards Medical Equipment Typical Application Circuits U1 5V IN 3 IN EZ5Z3L-3.3 2 OUT NC 3.3V OUT 1 U1 5V IN 3 IN EZ5Z3L-ADJ 2 OUT ADJ 1 0.1V to 3.7V OUT R1 R2  R1  VDROP = VREF  1+ R   2   VOUT = VIN − VDROP V R1 + R2 ≤ DROP 300 µA Revision 1, January 2001 1 www.semtech.com EZ5Z3L POWER MANAGEMENT Absolute Maximum Ratings Parameter Power D i ssi pati on C onti nuous C urrent Thermal Resi stance Juncti on to Ambi ent SOT-223 TO-220 TO-92 Thermal Resi stance Juncti on to C ase SOT-223 TO-220 TO-92 Operati ng Ambi ent Temperature Range Operati ng Juncti on Temperature Range Storage Temperature Range Lead Temperature (Solderi ng) 10 Sec.
