MAX38902E 14V Low Noise 500mA LDO Linear RMS Regulator General Description Benefits and Features The MAX38902E is low-noise linear regulator that delivers Delivers Flexible Operating Range up to 500mA of output current with only 14V of out- 1.7V to 5.5V Input Voltage Range RMS put noise from 10Hz to 100kHz. This regulator maintains 0.8V to 5.0V Output Voltage Range 1% output accuracy over a wide input voltage range, 500mA Maximum Output Current requiring only 100mV of input-to-output headroom at full 100mV Maximum Dropout at 500mA Load (3.6V ) IN load. The 600A no-load supply current is independent of < 0.1A Shutdown Supply Current dropout voltage. Reduces Noise and Improved Accuracy The MAX38902E has a resistor adjustable output voltage 14uV Output Noise, 10Hz to 100kHz RMS in the range of 0.8V to 5.0V and includes an active-low 600A Operating Supply Current POK output. The device features a programmable output 45dB PSRR at 100kHz soft-start rate, output over-current and thermal overload 1% DC Accuracy Over Load, Line, and protection. Temperature The MAX38902E is offered in an 8-pin TDFN package.

Package Information TDFN Package Code T822+3C Outline Number 21-0168 Land Pattern Number 90-0065 Thermal Resistance, Single-Layer Board: Junction-to-Ambient ( ) 130C/W JA Junction-to-Case Thermal Resistance ( ) 8C/W JC Thermal Resistance, Four-Layer Board: Junction-to-Ambient ( ) 102C/W JA Junction-to-Case Thermal Resistance ( ) 8C/W JC For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
