MAX1974Smallest 1A, 1.4MHz Step-Down Regulators | Integrated Circuits (ICs) | 2 | Active | The MAX1973/MAX1974 are constant-frequency 1.4MHz pulse-width-modulated (PWM) current-mode step-down regulators. The output voltage can be set as low as 0.75V using an external voltage-divider, or it can be set to preset outputs of 1V, 1.5V (MAX1974), 1.8V, or 2.5V (MAX1973) without requiring external resistors. The MAX1973 also includes a voltage-margining feature that offsets the output voltage up or down 4% to facilitate board-level production testing.A fixed 1.4MHz operating frequency ensures operation outside the DSL frequency band, provides fast transient response, and allows the use of small external components. Only 4.7µF input and output ceramic capacitors are needed for 1A applications. Forced PWM operation ensures a constant switching frequency over all load conditions.Output voltage accuracy is ±1% over load, line, and temperature operating ranges. The MAX1973 features voltage margining; the MAX1974 provides a POK output to indicate when the output has reached 90% of its nominal regulation voltage. Both devices are available in small 10-pin µMAX® packages.ApplicationsCell Phone Base StationsCentral Office DSL and TelecomDSL and Wireless Modems/RoutersDSP/ASIC Core and I/O suppliesNetwork EquipmentOptical Modules |
MAX1976Low-Input-Voltage, 300mA LDO Regulators with RESET in SOT and TDFN | Integrated Circuits (ICs) | 26 | Active | The MAX1963A/MAX1976A low-dropout linear regulators operate from a +1.62V to +3.6V supply and deliver a guaranteed 300mA continuous load current with a low 100mV dropout. The high-accuracy (±0.5%) output voltage is preset to an internally trimmed voltage in the +0.75V to +3.0V range. An active-low, open-drain reset output remains asserted for at least 2.2ms (MAX1963A) or 70ms (MAX1976A) after the output voltage reaches regulation. These devices are offered in thin SOT23 and thin DFN packages. An internal pMOS pass transistor allows the low supply current to remain independent of load and dropout voltage, making these devices ideal for portable battery-powered equipment.ApplicationsCellular/Smart/PDA PhonesDSC, CD/MP3 PlayersNotebook/Handheld ComputersPCMCIA Cards |
