9 / 16 page STLM20 DC and AC characteristics 9/16 4 DC and AC characteristics This section summarizes the DC and AC characteristics of the device. The parameters in the DC and AC characteristics table that follows are derived from tests performed under the test conditions (see Table6 on page9). Designers should check that the operating conditions in their circuit match the operating conditions when relying on the quoted parameters. Table 6. DC and AC characteristics Sym Description Test condition(1) 1. Valid for ambient operating temperature: TA = –55 to 130°C or TA = –40 to 85°C; VCC = 2.7V (except where noted). Min Typ(2) 2. TJ = TA = 25°C. Max Unit VCC Supply voltage TA = –30°C to 130°C 2.4 5.5 V TA = –55°C to 130°C or –40°C to 85°C 2.7 5.5 V VO Output voltage TA = 0°C 1.8639 V Temperature to voltage error(3) VO = (–3.88E–6 * T2) + (–1.15E–2 * T) + 1.8639V 3. Error accuracy is between the measured and calculated output voltage at specified conditions of voltage, current, and temperature. TA = 25°C to 30°C ±1.5 °C TA = 125°C to 130°C ±2.5 °C TA = 80°C to 85°C ±2.1 °C TA = 0°C ±1.9 °C TA = –40°C ±2.3 °C TA = –55°C ±2.5 °C IQ Quiescent current 2.4V ≤ VCC ≤ 5.5V 4.8 8 µA Sensor gain (temperature sensitivity or average slope), VO = –11.77mV/°C * T + 1.860V –30°C ≤ TA ≤ 100°C –11.4 –11.77 –12.2 mV/°C Non-linearity –20°C ≤ TA ≤ 80°C ±0.4 % ΔIQ Change of quiescent current 2.4V ≤ VCC ≤ 5.5V 0.7 µA TCVO Temperature coefficient of quiescent current –11 nA/°C ISD Shutdown current VCC ≤ 0.8V 0.02 µA ZO Output impedance 0µA ≤ IL ≤ 16µA(4)(5) 4. With negative current flowing into STLM20 and positive current flowing out, can typically sink less than 1µA and source is 16µA. 5. Over the supply range of 2.4 to 5.5V. 160 Ω RegL Load regulation(6) 6. Measured at constant junction temperature, with pulse testing and low duty cycle. Output changes due to heating may be calculated by multiplying internal dissipation by thermal resistance. –2.5 mV RegI1 Line regulation 2.4V ≤ VCC ≤ 5.0V 3.3 mV/V RegI2 5.0V ≤ VCC ≤ 5.5V 11 mV |
