• Fixed and Adjustable Versions Available • Cellular Telephones
• Output Current up to 500mA • Portable Consumer Equipment
• Very Low Quiescent Current • Portable (Notebook) Computers
• Input-output Differential less than 0.5V • Battery Powered Systems
• Short Circuit Protection • Portable Instrumentation
• Internal Thermal Overload Protection • Radio Control Systems
• ENABLE Pin available in selected packages • CD/DVD drives GENERAL DESCRIPTION The AMS5105 series consists of positive fixed and adjustable voltage regulators ideally suited for use in battery-powered systems. These devices feature very low qu iescent current (500uA or less) when supplying loads up to 500mA, and a standby current less than 500nA when disabled using the ENABLE pin (a vailable in selected packages). These unique characteristics and the low input-output differential required for proper regulation (0.5V for output currents of 500mA) make the AMS5105 ideal for use in standby power systems. Internal current limiting and thermal shutdown features provide protection for all AMS5105 series devices regardless of package type. The AMS5105 is offered as fixed voltage regulators in the 5 lead SOT-23, SOT-89, SOT-223, and 8 lead SOIC packages, and as adjustable voltage regulators in the 5 lead SOT-23 and 8 lead SOIC packages. All devices in the 5 lead SOT-23 and 8 lead SOIC packages are provided with ENABLE pin.

For guaranteed performance limits and associat ed test conditions, see the Electrical Characteristics tables. Note 2: To ensure constant junction temperature, low duty cycle pulse testing is used. Note 3: Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for TA = TJ = 25°C. Note 4: The maximum allowable power dissipation is a function of the maximum junction temperature TJ(MAX), the junction-to ambient thermal resistance θJ-A and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using: Aθ-J AJ T-(MAX)TP(MAX) θ= Where the values of the junction-to-ambient thermal resistances are as follows: 220°C/W for 5 lead SOT-23 (M1) and 160°C/W for the molded plastic SO-8 (S). Note 5: Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured at 1V differential. Note 6: ENABLE Threshold Voltage levels are specified as a percentage of input voltage VIN. Quiescent current can be minimized by choosing VENABLE HIGH equal to VIN. Note 7: Time required for VOUT to reach 95% of output voltage setting after VENABLE is switched from 0V to VIN.
