Maxim’s MAX8840/MAX8841/MAX8842 ultra-low-noise, low-dropout (LDO), 150mA linear regulators are available in a tiny 1mm x 1.5 x 0.8mm microDFN package that enables a total solution size as small as 3.9mm2, including external components. Ideal for space-constrained designs, such as cellphones, smartphones, PDAs, and notebook PCs, the regulators operate from a 2 to 6V supply, making them optimal for single-cell, Li+ battery-powered applications. Battery time is maximized due to extremely low ground-pin current (40 microamps, typ. in operation, 50nA, typ. in shutdown). The MAX8840/MAX8841 support fixed output voltages of 1.5, 1.8, 2.5, 2.6, 2.7, 2.8, 2.85, 3.0, 3.3, and 4.5V. The MAX8842 allows any voltage between 1.225 and 4.5V to be programmed with a simple resistor-divider.
