2 / 10 page CAT6218 Doc. No. MD-10010 Rev. C 2 © Catalyst Semiconductor, Inc. Characteristics subject to change without notice PIN DESCRIPTIONS Pin # Name Function 1 VIN Supply voltage input. 2 GND Ground reference. 3 EN Enable input (active high); a 2.5MΩ pull-down resistor is provided. 4 BYP Optional bypass capacitor connection for noise reduction and PSRR enhancing. 5 VOUT LDO Output Voltage. BLOCK DIAGRAM Figure 2. CAT6218 Functional Block Diagram PIN FUNCTION VIN is the supply pin for the LDO. A small 1μF ceramic bypass capacitor is required between the VIN pin and ground near the device. When using longer connections to the power supply, CIN value can be increased without limit. The operating input voltage range is from 2.3V to 5.5V. EN is the enable control logic (active high) for the regu- lator output. It has a 2.5MΩ pull-down resistor, which assures that if EN pin is left open, the circuit is disabled. VOUT is the LDO regulator output. A small 1μF cera- mic bypass capacitor is required between the VOUT pin and ground for stability. For better transient response, its value can be increased to 4.7μF. The capacitor should be located near the device. ESR domain is 5mΩ to 500mΩ. VOUT can deliver a maxi- mum guaranteed current of 300mA. For input-to- output voltages higher than 1V, a continuous 300mA output current might turn-on the thermal protection. A 250Ω internal shutdown switch discharges the output capacitor in the no-load condition. GND is the ground reference for the LDO. The pin must be connected to the ground plane on the PCB. BYP is the reference bypass pin. An optional 0.01μF capacitor can be connected between BYP pin and GND to reduce the output noise and enhance the PSRR at high frequency. ABSOLUTE MAXIMUM RATINGS (1) Parameter Rating Unit VIN 0 to 6.5 V VEN, VOUT -0.3 to VIN + 0.3 V Junction Temperature, TJ +150 °C Power Dissipation, PD Internally Limited (2) mW Storage Temperature Range, TS -65 to +150 °C Lead Temperature (soldering, 5 sec.) 260 °C ESD Rating (Human Body Model) 3 kV RECOMMENDED OPERATING CONDITIONS (3) Parameter Range Unit VIN 2.3 to 5.5 V VEN 0 to VIN V Junction Temperature Range, TJ -40 to +125 °C Package Thermal Resistance (SOT23-5), θJA 235 °C/W Typical application circuit with external components is shown on page 1. Notes: (1) Exceeding maximum rating may damage the device (2) The maximum allowable power dissipation at any TA (ambient temperature) is PDmax = (TJmax – TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. (3) The device is not guaranteed to work outside its operating rating. BYP EN GND VIN VOUT VIN VOUT Shutdown Switch LDO Reference |
