MAX8510/MAX8511/ Ultra-Low-Noise, High PSRR, MAX8512 Low-Dropout, 120mA Linear Regulators General Description Features The MAX8510/MAX8511/MAX8512 ultra-low-noise, low- Space-Saving SC70 and TDFN (2mm x 2mm) Packages dropout (LDO) linear regulators are designed to deliver 11V Output Noise at 100Hz to 100kHz RMS up to 120mA continuous output current. These regulators Bandwidth (MAX8510) achieve a low 120mV dropout for 120mA load current. 78dB PSRR at 1kHz (MAX8510) The MAX8510 uses an advanced architecture to achieve 120mV Dropout at 120mA Load ultra-low output voltage noise of 11V and PSRR of RMS Stable with 1F Ceramic Capacitor for Any Load 54dB at 100kHz. Guaranteed 120mA Output The MAX8511 does not require a bypass capacitor, hence Only Need Input and Output Capacitors (MAX8511) achieving the smallest PC board area. The MAX8512s Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, output voltage can be adjusted with an external divider. 2.85V, 3V, 3.3V, 4.5V (MAX8510/MAX8511) and The MAX8510/MAX8511 are preset to a variety of voltag- Adjustable (MAX8512) es in the 1.5V to 4.5V range. Designed with a P-channel Low 40A Ground Current MOSFET series pass transistor, the MAX8510/MAX8511/ Excellent Load/Line Transient MAX8512 maintain very low ground current (40A). Overcurrent and Thermal Protection The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8510 Ordering Information requires only 1F (typ) of output capacitance for stability PART* TEMP RANGE PIN-PACKAGE with any load. When disabled, current consumption drops MAX8510EXKxy+T -40C to +85C 5 SC70 to below 1A. *xy is the output voltage code (see Output Voltage Selector Package options include a 5-pin SC70 and a tiny 2mm x Guide). Other versions between 1.5V and 4.5V are available in 2mm x 0.8mm TDFN package. 100mV increments. Contact factory for other versions. +Denotes a lead(Pb)-free/RoHS-compliant package.
