The 16 V NCR32xx and 40 V NCR42xx series are available in two package styles, the space-saving SOT457 (SC-74) and the SOT223 (SC-73), a slightly-larger option which delivers a higher-power capability of up to 1250mW. The LED drivers feature an accurate, stabilized output current of 10mA without an external resistor; if an external resistor is used then the output current is adjustable up to 250 mA. Voltage overhead is low at 1.4 V. For extra ruggedness, the junction temperature of the drivers is 150 °C.
