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.

• 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 A Typical
• Full−load Ground Current of 160 A 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
