TC1017-2.8VLTTR Microchip

TC1017 150 mA, Tiny CMOS LDO With Shutdown Features: General Description: The TC1017 is a high-accuracy (typically 0.5%) Space-saving 5-Pin SC-70 and SOT-23 Packages CMOS upgrade for bipolar Low Dropout regulators Extremely Low Operating Current for Longer (LDOs). It is offered in a SC-70 or SOT-23 package. Battery Life: 53 A (typ.) The SC-70 package represents a 50% footprint reduc- Very Low Dropout Voltage tion versus the popular SOT-23 package and is offered Rated 150 mA Output Current in two pinouts to make board layout easier. Requires Only 1 F Ceramic Output Capacitance Developed specifically for battery-powered systems, High Output Voltage Accuracy: 0.5% (typical) the TC1017s CMOS construction consumes only 10 s (typ.) Wake-Up Time from SHDN 53 A typical supply current over the entire 150 mA operating load range. This can be as much as 60 times Power-Saving Shutdown Mode: 0.05 A (typ.) less than the quiescent operating current consumed by Overcurrent and Overtemperature Protection bipolar LDOs. Pin-Compatible Upgrade for Bipolar Regulators The TC1017 is designed to be stable, over the entire input voltage and output current range, with low-value Applications: (1 F) ceramic or tantalum capacitors. This helps to Cellular/GSM/PHS Phones reduce board space and save cost. Additional inte- grated features, such as shutdown, overcurrent and Battery-Operated Systems overtemperature protection, further reduce the board Portable Computers space and cost of the entire voltage-regulating Medical Instruments application. Electronic Games Key performance parameters for the TC1017 include Pagers low dropout voltage (285 mV typical at 150 mA output current), low supply current while shutdown (0.05 A typical) and fast stable response to sudden input voltage and load changes.

Load regulation is tested over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal regulation specification. 5: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value at a 1V differential. 6: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a current pulse equal to I at V = 6V for t = 10 msec. LMAX IN 7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction-to-air (i.e., T , T , ). Exceeding the maximum allowable power A J JA dissipation causes the device to initiate thermal shutdown. Please see Section 5.1 Thermal Shutdown, for more details. 8: Output current is limited to 120 mA (typ) when V is less than 0.5V due to a load fault or short-circuit condition.
