TPS79918DDC Datasheet

Low Dropout Regulators - LDO


The TPS79918DDC family of low-dropout (LDO)low-power linear regulators offer excellent ACperformance with very low ground current. Highpower-supply rejection ratio (PSRR), low noise, faststart-up, and excellent line and load transientresponse are provided while consuming a very low40mA (typical) ground current. The TPS799xx isstable with ceramic capacitors and uses an advancedBiCMOS fabrication process to yield dropout voltagetypically 100mV at 200mA output. The TPS799xxuses a precision voltage reference and feedback loopto achieve overall accuracy of 2% over all load, line,process, and temperature variations. It is fullyspecified from TJ = –40°C to +125°C and is offered inlow profile ThinSOT23, Wafer Chip-Scale (WCSP),and 2mm × 2mm SON packages, ideal for wirelesshandsets and WLAN cards. TPS79918DDC Features • 200mA Low Dropout Regulator with EN• Low IQ: 40mA• Multiple Output Voltage Versions Available:– Fixed Outputs of 1.2V to 4.5V UsingInnovative Factory EEPROM Programming– Adjustable Outputs from 1.20V to 6.5V• High PSRR: 66dB at 1kHz• Ultra-low Noise: 29.5mVRMS• Fast Start-Up Time: 45ms• Stable with a Low-ESR, 2.0mF Typical OutputCapacitance• Excellent Load/Line Transient Response• 2% Overall Accuracy (Load/Line/Temp)• Very Low Dropout: 100mV• ThinSOT-23, WCSP, and 2mm × 2mm SON-6Packages TPS79918DDC Applications • Cellular Phones• Wireless LAN, Bluetooth®• VCOs, RF• Handheld Organizers, PDAs
