LT1963A - 1.5A, Low Noise, Fast Transient Response LDO …

1 LT1963A Series , Low Noise, Fast Transient Response LDO regulators Features Description n Optimized for Fast Transient Response The LT 1963A series are low dropout regulators optimized n Output Current: for fast Transient Response . The devices are capable of n Dropout voltage : 340mV. supplying of output current with a dropout voltage of n Low Noise: 40 V. RMS (10Hz to 100kHz) 340mV. Operating quiescent current is 1mA, dropping to n 1mA Quiescent Current < 1 A in shutdown. Quiescent current is well controlled; it n No Protection Diodes Needed does not rise in dropout as it does with many other regula- n Controlled Quiescent Current in Dropout tors.

2 In addition to fast Transient Response , the LT1963A . n Fixed Output Voltages: , , , regulators have very low output noise which makes them n Adjustable Output from to 20V. ideal for sensitive RF supply applications . n < 1 A Quiescent Current in Shutdown Output voltage range is from to 20V. The LT1963A . n Stable with 10 F Output Capacitor*. regulators are stable with output capacitors as low as n Stable with Ceramic Capacitors*. 10 F. Internal protection circuitry includes reverse bat- n Reverse Battery Protection tery protection, current limiting, thermal limiting and n No Reverse Current reverse current protection.

3 The devices are available in n Thermal Limiting fixed output voltages of , , , and as n 5-Lead TO-220, DD, 3-Lead SOT-223 and an adjustable device with a reference voltage . The 8-Lead SO Packages LT1963A regulators are available in 5-lead TO-220, DD, 3 lead SOT-223, 8-lead SO and 16-lead TSSOP packages. applications L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and ThinSOT is a trademark of Linear Technology Corporation.
