MyMaxim SubscriptionsProduct Details
The MAX8510/MAX8511/MAX8512 ultra-low-noise, low-dropout (LDO) linear regulators are designed to deliver up to 120mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8510 uses an advanced architecture to achieve ultra-low output voltage noise of 11µVRMS and PSRR of 54dB at 100kHz.
The MAX8511 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8512's output voltage can be adjusted with an external divider.
The MAX8510/MAX8511 are preset to a variety of voltages in the 1.5V to 4.5V range. Designed with a P-channel MOSFET series pass transistor, the MAX8510/MAX8511/MAX8512 maintain very low ground current (40µA).
The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8510 requires only 1µF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1µA.
Package options include a 5-pin SC70 and a tiny 2mm x 2mm x 0.8mm TDFN package.

Description
The MAX11205PMB1 peripheral module provides the necessary hardware to interface the MAX11205 16-bit ADC to any system that utilizes Pmod™-compatible expansion ports configurable for GPIO interface. The IC is an ultra-low-power (< 300µA max active current), high-resolution, serial-output ADC. This device provides the highest resolution per unit power in the industry and is optimized for applications that require very high dynamic range with low power, such as sensors on a 4mA to 20mA industrial control loop. The voltage reference for the IC is supplied by a MAX6037 (2.5V) that is also on the module. The filtered power-supply voltage from the host can be optionally passed (jumper selectable) through a MAX8510 ultra-low-noise LDO, allowing empirical evaluation of performance with different power sources.
Refer to the MAX11205 IC data sheet for detailed information regarding operation of the IC.
