1 / 10 page © Semiconductor Components Industries, LLC, 2009 December, 2009 − Rev. 1 1 Publication Order Number: CAT6221/D CAT6221 300 mA CMOS Dual LDO Regulator Description The 300 mA CMOS Dual LDO CAT6221 combines in a single TSOT−23 6−lead package two low dropout regulators (LDO), each with its own enable pin. The regulator outputs drive loads up to 300 mA. By design, the dual LDO provides fast response time during load current and line voltage changes. Each LDO is optimized for low noise and high crosstalk isolation. With zero shut down current and a low quiescent current of 100 mA, the dual LDO is ideal for battery−operated devices with supply voltage from 2.3 V to 5.5 V. The dual LDO offers 1% initial accuracy and very low dropout voltage, typical 210 mV at 300 mA. Stable operation is provided with small 1 mF ceramic output capacitors, reducing required board space and component cost. Other features include fold−back current limit and thermal protection. The dual LDO is available in the tiny 6−lead TSOT−23 package with a maximum height of 0.8 mm. Features • Two Outputs with Guaranteed 300 mA Peak Output Current • Low Dropout Voltages of 210 mV Typical at 300 mA • Stable with Ceramic Output Capacitors • Independent Enable Pins • Under Voltage Lockout • No−load Ground Current of 100 mA Typical • Full−load Ground Current of 160 mA Typical • ±1.0% Output Voltage Initial Accuracy (VOUT ≥ 2.0 V) • ±2.0% Accuracy Over Temperature (VOUT ≥ 2.0 V) • “Zero” Current Shutdown Mode • Fold−back Current Limit and Thermal Protection • TSOT−23 6−lead, 0.8 mm Height Package • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant Applications • Cellular Phones • Battery−powered Devices • Consumer Electronics http://onsemi.com TSOT−23 TD SUFFIX CASE 419AF PIN CONNECTIONS T3YM MARKING DIAGRAM 1 6 (Top View) VOUT1 VOUT2 EN1 VIN EN2 1 See detailed ordering and shipping information in the package dimensions section on page 10 of this data sheet.
