FT533IA

Fremont Micro Devices FT533xx Fast Start-up, Ultra Low Noise, High PSRR, 400mA LDO FEATURES DESCRIPTION ¾ Ultra-Low Noise for RF Application The FT533xx is designed for portable RF and ¾ Ultra-Fast Response in Line/Load Transient wireless applications with demanding performance ¾ Quick Start-Up (Typically 25μS) and space requirements. The FT533xx performance is ¾ Low Quiescent Current: 65μA optimized for battery powered systems to deliver ¾ Less than 0.1μA Standby Current When ultra low noise and low quiescent current. Regulator Shutdown ground current increases only slightly in dropout, Low Dropout Voltage: 100mV @ 100mA, further prolonging the battery life. ¾ 420mV @ 400mA (Vout=2.8V) ¾ Wide Operating Voltage Ranges : 2.5V to 6V The FT533xx also works with low-ESR ceramic ¾ TTL-Logic-Controlled Shutdown Input capacitors, reducing the amount of board space ¾ Low Temperature Coefficient necessary ¾ Current Limiting Protection hand-held wireless devices. The FT533xx consumes ¾ Only 1μF Output Capacitor Required less than 0.1μA in shutdown mode and has fast ¾ High Power Supply Rejection Ratio turn-on time less than 25μS. The other features ¾ ROHS Compliant and 100% Lead (Pb)-Free include low dropout voltage, high output accuracy, ¾ Custom Voltage Available current limiting protection, and high ripple rejection ¾ Custom Options for CE Logic and Build-in ratio. The FT533xx is available in the 5-lead of Pull-up/down Available SOT-23-5(L), SC-70 and the 3-lead of SOT-23-3(L), for power applications, critical in SOT-89-3(L), SOT-23 packages. APPLLICATIONS ¾ CDMA/GSM Cellular Handsets ¾ Battery-Powered Equipment ¾ Laptop, Palmtops, Notebook Computers ¾ Hand-Held Instruments ¾ PCMCIA Cards ¾ Portable Information Appliances www.fremontmicro.com Page 1 of 21 DS533-A2 Fremont Micro Devices FT533xx TYPICAL APPLICATION CIRCUIT Figure 1: Typical Application Circuit ABSOLUTE MAXIMUM RATINGS Š Supply Input Voltage ----------------------------------------------------------------------------------------------------- 6V Š Power Dissipation, PD@ TA=27 ୅ SOT-23-5(L) ---------------------------------------------------------------------------------------------------- 400mW SOT-23-3(L) ---------------------------------------------------------------------------------------------------- 400mW SOT-89-3(L) ---------------------------------------------------------------------------------------------------- 600mW SC-70 ------------------------------------------------------------------------------------------------------------ 300mW SOT-23 ----------------------------------------------------------------------------------------------------------- 250mW Š Package Thermal Resistance ć/W SOT-23-3(L) --------------------------------------------------------------------------------------------------- 250ć/W SOT-89-3(L) --------------------------------------------------------------------------------------------------- 170ć/W SC-70 ----------------------------------------------------------------------------------------------------------- 330ć/W SOT-23 --------------------------------------------------------------------------------------------------------- 380ć/W Lead Temperature (Soldering, 10sec.) ------------------------------------------------------------------------------ 260ć Š Storage Temperature Range -----------------------------------------------------------------------------ˉ60ć to 150ć SOT-23-5(L) --------------------------------------------------------------------------------------------------- 250 Š ESD Susceptibility HBM (Human Body Mode) -----------------------------------------------------------------------------------------4kV MM (Machine Mode) --------------------------------------------------------------------------------------------200V * Stresses exceed those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
