LDLN015 150 mA - ultra low noise - high PSRR linear voltage regulator IC Datasheet - production data Description The LDLN015 is an ultra low noise linear regulator which provides 150 mA maximum current from an input voltage ranging from 2.1 V to 5.5 V with a typical dropout voltage of 86 mV. With its 6.3 VRMS noise value in a band from 10 Hz to 100 kHz, the LDLN015 provides a very clean output suitable for ultra sensitive loads. It is stable with ceramic capacitors. High PSRR, low quiescent current and very low noise features make it suitable for low power battery powered Features applications. Power supply rejection is higher Ultra low noise: 6.3 VRMS from 10 Hz to than 90 dB at low frequencies and starts to roll off 100 kHz at 10 kHz. The enable logic control function puts Input voltage from 2.1 to 5.5 V the LDLN015 into shutdown mode allowing a Very low quiescent current (35 A typ. at no total current consumption lower than 1 A. The load, 70 A typ. at 150 mA load 2 A max. device also includes a short-circuit constant in off mode) current limiting and thermal protection. Typical Output voltage tolerance: 1% at 25 C applications are noise sensitive loads like ADC, 150 mA guaranteed output current VCO in mobile phones, and personal digital Wide range of output voltage from 0.8 V to assistants (PDAs). 3.3 V with 100 mV step Logic-controlled electronic shutdown Compatible with ceramic capacitor (C = 0.47 F) OUT No bypass capacitor is required Internal current and thermal limit Package DFN6 (2 x 2 mm) Temperature range: - 40 C to 125 C Table 1: Device summary Order code Output voltage (V) LDLN015PU10R 1.0 LDLN015PU12R 1.2 LDLN015PU15R 1.5 LDLN015PU18R 1.8 LDLN015PU25R 2.5 LDLN015PU28R 2.8 LDLN015PU30R 3.0 LDLN015PU33R 3.3 May 2017 DocID022735 Rev 5 1/16 www.st.com This is information on a product in full production.
