The output voltage is preset at an internally trimmed voltage 1.8V. 2.5V or 3.3V. Other output voltages can be mask-optioned from 1.4V to 4.4V with 100mV increment. The AP1735 consists of a 1.25V bandgap reference, an error amplifier, and a P-channel pass transistor. Other features include short-circuit protection and thermal shutdown protection. The AP1735 devices are available in SOT-89 packages. ▓ TYPICAL APPLICATION CIRCUITS All reserved by AnSC © 2007 Page: 1/9 2007/12/19 AP1735 Series 600mA LDO Linear Regulator Anwell Semiconductor Corp. ▓ ABSOLUTE MAXIMUM RATINGS Parameter Input voltage VIN to GND Output current limit, I(LIMIT) Junction Temperature Power Dissipation SOT-89 Operating Ambient Temperature Storage Temperature Lead temperature (soldering, 10sec) Thermal Resistance SOT-89 Symbol Vin Iout TJ Pd Topr Tstg θJA Ratings 7.0 1.3 +155 550 -40 ~ +125 -55 ~ +150 +250 180 Units V A ℃ mW °C °C °C °C/W * The power dissipation values are based on the condition that junction temperature TJ and ambient temperature TA difference is 100°C. * Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and function operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied.
