CAT6219-330TDGT3

CAT6219 500 mA CMOS LDO Regulator Description The CAT6219 is a 500 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes. The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150 ms. With zero shutdown current and low ground current of 55 mA typical, the CAT6219 is ideal for battery-operated devices with supply voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit disables the output at supply voltages under 2.15 V typical. The CAT6219 offers 1% initial accuracy and low dropout voltage, 300 mV typical at 500 mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and component cost. Other features include current limit and thermal protection. The LDO is available in fixed and adjustable output in the low profile (1 mm max height) 5−lead TSOT23, 6−pad 1.5 mm x 1.5 mm WDFN and in the 6−pad 2 mm x 2 mm TDFN packages. http://onsemi.com 5 1 TSOT−23 TD SUFFIX CASE 419AE 1 OUT IN VOUT NC/ADJ NC EN GND BYP/ADJ WDFN−6 1 VIN GND EN TSOT−23 • Cellular Phones • Battery−powered Devices • Consumer Electronics 1 BYP/ADJ TAB NC VOUT VIN TDFN−6 MARKING DIAGRAMS RVYM USYM UMYM US = CAT6219−125, CAT6219−250, = CAT6219−300 Device Code RV = CAT6219−180, CAT6219−280, = CAT6219−285, CAT6219−330 Device Code UM = CAT6219−ADJ Device Code Y = Production Year (last digit) M = Production Month: 1 − 9, A, B, C ABYM (TDFN) AB = CAT6219180, CAT6219VP5 Device Code Y = Production Year (last digit) M = Production Month: 1 − 9, A, B, C TM Applications EN GND (Top Views) Guaranteed 500 mA Peak Output Current Low Dropout Voltage of 300 mV Typical at 500 mA Stable with Ceramic Output Capacitor External 10 nF Bypass Capacitor for Low Noise Quick−start Feature Under Voltage Lockout No−load Ground Current of 55 mA Typical Full−load Ground Current of 85 mA Typical ±1.0% Initial Accuracy (VOUT ≥ 2.0 V) ±2.0% Accuracy Over Temperature (VOUT ≥ 2.0 V) “Zero” Current Shutdown Mode Fold−back Current Limit Thermal Protection 5−lead TSOT−23, 6−pad WDFN and TDFN Packages These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant 1 TDFN−6 VP5 SUFFIX CASE 511AH PIN CONNECTIONS Features • • • • • • • • • • • • • • • 1 WDFN−6 MV2 SUFFIX CASE 511BJ T S U V M SM UM VM (WDFN) = CAT6219−285MV2 Device Code = CAT6219−280MV2 Device Code = CAT6219−330MV2 Device Code = CAT6219−ADJMV2 Device Code = Date Code ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 11 of this data sheet. © Semiconductor Components Industries, LLC, 2012 September, 2012 − Rev. 14 1 Publication Order Number: CAT6219/D CAT6219 VIN 2.3 V to 5.5 V OFF CIN VIN 1 mF ON VOUT COUT 2.2 mF VOUT CAT6219 EN BYP GND VIN CBYP (Optional) 10 nF Figure 1.

A small 2.2 mF ceramic bypass capacitor is required between the VOUT pin and ground. For better transient response, its value can be increased to 4.7 mF. The capacitor should be located near the device. For the SOT23-5 package, a continuous 500 mA output current may turn-on the thermal protection. A 250 W 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. LDO Output Voltage. To be connected to the ground plane on PCB Pin Function VIN is the supply pin for the LDO. A small 1 mF 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 2.3 V to 5.5 V. BYP is the reference bypass pin. An optional 0.01 mF capacitor can be connected between BYP pin and GND to reduce the output noise and enhance the PSRR at high frequency. ADJ is the adjustable input pin for the adjustable LDO. The pin is connected to the resistor voltage divider. Table 2.
